1.) Finding a topic

After establishing who is interested in being a member of this year’s Team, everyone went out to find possible supervisors and projects. Prof. Rolf Daniel together with Dr. Elzbieta Brzuszkiewicz and Dr. Silja Brady, whom some of us know from the first microbiology lab course, have a project for us:

2.) Project Proposal

We would create a cellulosome like multi enzyme scaffold as well as several linker regions with which

enzymes of interest could be fused. This way, if for example a company wants to degrade different

materials in a solution or wants a specific enzyme complex they would then list the needed enzymes

and order them from us. We would then transform the enzymes before / after the linker regions, the

enzymes would be assembled in the cell on the scaffold and then exported by the model organism.

As the scaffold itself could be easily tagged, i.e. by a strep tag, we could then purify the multi enz

yme complex and deliver it to the company. As there are enzymes for thousands of different reactions, the applicability would be broad. As Dr. Brzuszkiewicz and Dr. Brady weren't sure whe

ther something like this has already been done, we will still have to do some research into the topic itself.

2.) Deciding which topic to choose

As we currently have a grand total of one project, the question is whether we wait for other topics,

as not all lecturers have answered yet or, if there are no objections, go ahead with the project of

Prof. Daniel. For this, please sent me a mail with your thoughts until Sunday, as we need to decide fast.

3.) Distribution of tasks

Everybody should look into Prof. Daniels topic, to see whether something similar has been done and

what the current status on this research area is. In the coming days Verena will invite you to the

iGEM 2015 Dropbox folder, in which you can upload interesting papers.

Booklet: Dennis agreed to do the first draft over the holidays, Avril mentioned that she could proof

read the english version, Stefani would help with the design and further improvement.

Fiscal management : David and Joshy have agreed to try and set up a preliminary budget plan.

Logo: Stefani will design our first logo.

Wikipedia: Joshy agreed to handle our wikipedia for the time being.

Music video: Verena has big plans for a laboratory-themed song and corresponding music video.

Website: we still need someone who either knows a bit about website design or wants to learn how

to set up a web site. We can use the old site as template, but we still need to convert/cannibalise it

into our own. Please mail Verena or me if you would like to try your hand as a web designer.

4.) Dismissing members

We are a comparatively small group with an ambitious project and a limited number of members. The coming months are very important, since this decides pretty much how easy we will have it later in the year. We currently have registered everybody who either mailed Verena or Julian or came to one of our meetings and are currently at 10 members total, 12 being the limit. If we get to the limit,we have to put people on the waiting list. Since we are a small group with an ambitious project, having someone in the group who doesn't bother to cancel to agreed appointments or, worse, won't do work she/he agreed on doing, would not only unnecessary aggravate the rest of the group but would also slow us down.

Therefore, with the coming meeting, we will introduce a three strike system. If you can't come to a meeting, that's no problem - just tell someone who will attend in advance or post it on facebook. If you don't do so three times, you will be excluded from the iGEM group.

If someone keeps making trouble within the group, the organisation team reserves the right to vote on excluding them.

1.) Topic:

We intend to utilise a scaffold protein in order to assemble enzymes with different functions into one complex, which will hopefully increase their efficiency as well as being customisable.

As model organisms B.subtilis or E.coli seem to be to most viable at this point

Issues may arise from the connection of linker regions to the enzymes and the subsequent loss of function.

2.) Booklet:

Most parts of the booklet have been written by Dennis. Avril will proofread the sections and then pass them on to Stefani for layout and design.

Further information needs to be added about the research projec, budget and sponsoring.

3.) Website/Wiki:

Udhaya and Joschy will take care of the Wiki and Webpage together. Bing Yao from a previous Igem Team has offered to help and teach.

4.) Locations:

Julian has asked Prof. Daniel to ask if someone has a space for us to have an office in their lab. Other options are the Schwann-Schleiden Research Centre, experimental medicine or the physics department.

Update: Verena has found out, that there is an iGem Computer in the Microbiology library.

Usage of the practical room as labspace is in an agreement, and should therefore be possible.

Equipment from the previous team will be assessed by Verena.

5.) Organisation Team was confirmed in its current setup of: Julian, Verena, Udhaya and Avril. If desired or the need should arise, the team can be extended further along the line.

6.) Finances:

Budget for 3 different situations can be found in the dropbox (by Daniel). The booking prices are from the 5th of January and are subject to change.

Visa prices need to be determined and passports updated.

Julian will take over the Finances including the management of a bank account, bookings and the overview of our spending and financial support.

Update: 200€ are left over from the previous Igem Team to be used by this Igem Team.

7.) Timetable and Deadlines:

Julian has made a preliminary timetable (Dropbox). In addition to this, the deadline for the booklet will be the 14th of January and the deadline for the first round of Sponsor contacting will be the 18th of January. Unresponsive sponsors will be contacted weekly. The sponsor list will be split up between the team members at the next meeting (13th of January).

The best weekdays for team meetings are Mondays and Thursdays .

8.) Roles:

Press and Publicity: Steffi and Dennis

Finances: Julian

Sponsoring managers: Sindhu and Nida

1.) Logo and Booklet:

Stefani presented two ideas for a possible logo and asked for opinions. She will flesh them out a bit and we can decide on our next meeting which one we will choose as our main logo.

Stefani also presented a possible design for our booklet.

Udhaya had an idea for a possible slogan we could use, fitting one of our possible logos: “Placing enzymes where they should be”.

2. ) Sponsors:

Sindhu will assign the companies we have so far, so everyone will have to contact 4 to 5.

3.) Equipment:

Verena and Udhaya went through the inherited things from last year’s iGEM-Group. They are now listed in our inventory.

4.) Meetings:

We decided to only hold meetings every two weeks, as every week seems a bit excessive, especially when we meet alternative on Mondays and Tuesdays. The schedule is in our timetable.

5.) Task for next week:
Everybody should think about a fitting project title until our next meeting.

Present: Verena, Alaa, Udhaya, Julian, Daniel, Avril, Silja, Ela, Prof. Daniel, Heiko Liesegang

Supervisors will be met for monthly update

1.) Useful contacts:

Supervisors Ela (Sequencing) and Silja (Biotech), Head of Unit Prof. Daniel, Bioinformatics Heiko Liesegang, Secretary Daniela, Lab Technicians: Ute & Gabriele, Synthetic Bio Jun.-Prof. Neumann.

Prof. Daniel will meet with Prof. Braus to discuss grants, which will probably require writing a formal letter

Petra from Prof. Daniel's lab used to work as a webdesigner and can be asked for support on the webpage

Supervisors will check the current sponsor list for additional contacts

Silja will do the lab safety talk before we start the labwork

Heiko Liesegang is happy to support the team with Bioinformatics and Industrial appliance of the project (he is situated in the cellar).

Verena will add the supervisors to the dropbox, so they can have access to the list of sponsors, inventory, etc.

2.) Project:

The scaffold protein will be taken from Clostridium thermocellum, which is very well described and has been fully sequenced, as well as a known structure. The host will be codon optimised E.coli, which can be used with a vector system and can have the structure expressed intra- or extracellularly. -> Proof of principle on E.coli before large scale adaptation with B.subtilis

3.) Research to be done by team:

- Which enzymes: ideally well known

- How many "dockerins" on the scaffold

- Which biotechnical processes offer themselves -> e.g. waste water, cow udders

- How can the enzymes be linked to the scaffold: e.g multiple enzymes with the same dockerin for exchangeability

- Which Tags can be used

- Which cloning techniques

- Will the bacteria survive and work continuously or die after their application

- How will they be removed from the product

Ideally we would use a vector system to form a toolkit, which can be modified by the customers. Therefore a modular design and simplicity would be of advantage.

4.) Planning: Times expected time by 2 or split group into teams, which work on separate goals: e.g. Scaffold group, lipolytic enzymes group, cellulolytic enzymes group, etc.

Each group should work with multiple enzymes, to guarantee that they create at least one functional tool.

5.) Labwork:

Can start at any time as the Daniel-group will provide us with the resources until we have raised enough money. This can then be paid back at a later state. Kits and essential chemicals, etc. are also available through the Lab. -> Start on the Scaffold can begin. Julian, Udhaya and Verena will meet Silja on Tuesday to create the theoretical basis/Clone manager plans.

6.) Meetings will have to take place at least weekly as soon as the labwork has started. Next monthd need to be planned and scheduled with everyone's availability and working ability, exams, etc.

7.) Logo will have added science things, e.g. helix, magnifying glass. The theme should be used with the university colours (dark and light blue). The booklet can have a different title layout to the main part, which can also be designed in a modular, toolbox manner.

Think of a name for the cellulosome & make it cool: e.g.: superosome, flexosome, legosome

8.) Sponsors:

Possible other sponsors: IVA (for kits), Illumina, Roche

Present: Silja, Ela, Julian, Verena, Avril, Stefani, Joschi, Sindhu, Nida, Alaa, Dennis, Daniel

Student Card numbers were collected for easier access to the labs.

1.) Project:

We need to decide whether we want the enzymes to degrade or synthesis and focus on one application to start with.

Possible enzymes/applications: nitrilases, university waste water/water works/ environmental, contaminated soils, TNT degrading, rubber degrading, Vitamin production from intermediates (can be easily proven if it works), bacterial indigo synthesis/other colours

The easiest is to take a lipase, esterase and/or phosphatase and see if it can degrade different substrates.

Ela emphasized that the labbooks need to be written with particular care in order to keep the overview and find small mistakes.

A time plan and team division should be formed in the near future.

The safety lecture will be given on Monday the 26.1.2015 at 10am. Everyone is required to attend this lecture!

2.) Booklet:

Projectname was decided: Flexosome (with 10/12 votes), runners up were: Custosome and Supersome

IGEM logo should be within the text to minimise white space

A group picture should be added to make the booklet more personal.

Boxes on page 1 need to be filled/removed/changed

3.) Sponsoring packages:

Bronze package: >500€: Logo will be displayed on the website

Silver: >2500€: Logo on Website and T-Shirt

Gold: >5000€: Logo will be displayed everywhere

4.) Sponsors:

Contacts exist to Henkel, Bayer & Illumina. Silja and Ela will introduce us to these and then we can send our booklet/proposal for funding.

Other possible sponsors are: SI clone manager or VWR

Attendance

Avi, Udhaya, Nida, Verena and Julian

1.) Booklet:

Avi and Stefani went to the printer center, they test-printed a booklet and gave some options and prices. They showed the booklet to Ela and she also talked to Prof. Daniel. He wants the logo and booklet to have more biology related design on it and he wants it to be printed on better paper. His working group can pay for it. So Stefani is still working on the booklet. The printing can be done on Din A3 sized paper which will reduce costs (30 € for 80 booklets!?) For a professional binding we have to give it to a Buchbinder, Avi had contacted the Buchbinder and the guy said the costs will be 20 € for half an hour and 40 € if it takes a full hour.

2.) Sponsoring:

Sindhu and Nida divided our company list. Each person has to contact 6 companies. The updated list is in the Dropbox.

3.) iGEM GWDG account and email address:

Verena contacted the GWDG and filled in the form to create an iGEM 2015 user account incl. email-address. As soon as it is done, the GWDG will send a letter to Prof. Daniels department.

4.) Bachelor students from other faculties:

Debbie asked a friend who is studying B. Sc. Informatics here in Göttingen and he is interested in participating to help with programming and stuff for the website. Since he is focussing on a different area but does not seem to be completely uneducated in websites and webdesign and is 24 years old, we decided that if we cannot find another skilled (younger) person, we can try it.

5.) Group photo

A preliminary group photo was taken last week and will be included in the booklet as long as we don’t have another one.

6.) Scaffoldin

Udhaya, Julian and Verena met up with Ela and Silja to further design the Scaffoldin. On the first meeting some interesting organisms for putative cohesins/dockerins could be found. Now Ela compared a variety of cohesin structures (sequences) from those organisms by alignment and bioinformatical reconstruction of phylogenetic trees. Ela gave all organisms a letter code. For example: “CTHE” for Clostridium thermocellum. Due to the fact that we want to use (only) 4 different cohesins, we need to cut off scaffoldin proteins that naturally offer more than 4 cohesins in the protein structure. To ensure that there will be no unexpected interactions with our desired cohesins (and to have a back-up if the first construct doesn’t work), we finally decided to go with a naturally long scaffoldin protein and a shorter one which only harbors 4 cohesin places:

1) Main construct : Clostridium thermocellum

Scaffolding protein CipA (cohesin type I) with dockerin type II. CipA contains in sum 9 cohesins. The first two are somehow disconnected by a CBM (cellulose binding motif). A deletion could lead to problems, so we decided to cut off cohesion 1-4 (incl. the CBM). The resulting protein offers space for 5 cohesins. The first of these 5 will be the natural cohesin of C. thermocellum so that we have 4 free cohesin places for our desired cohesins.

Desired Scaffolding protein structure:

SP EC – linker 6 CTHE – coh6 (CTHE) – cohX – cohY – cohZ – DOC (CTHE)

2) Back-Up: Acetivibrio cellulolyticus

Scaffolding protein ScaB (cohesin type II) with dockerin type I. ScaB contains in sum 4 cohesins. The first of these 4 will be (again) the natural cohesin of A. cellulolyticus so that we have 3 free cohesin places for our desired cohesins. It is not clear at the moment which dockerin will be used at the end of the structure.

Desired Scaffolding protein structure:

SP EC – coh type II – cohX – cohY – cohZ – DOC (ACEL) / DOC (CTHE)

For further information on the scaffoldin please look in the “Scaffoldin” Dropbox-folder: PowerPoint “scaffoldin_overview”

3)Websites/tools : NCBI (BLAST etc.), InterPro Scan for sequences, alignments, selection and branding of domains in Artemis.

Calculated 3D structures of CipA (Clostridium thermocellum) by LOOPP and Phyre²

What has to be done now is to find the sequences for the fitting dockerin-binding proteins. This will be discussed on the next scaffolding-meeting tomorrow (03.2.15, 2 p.m.) with Ela, Silja, Udhaya, Julian and Verena.

Moreover it is time for us to contact companies doing gene synthesis. Possible companies can be found at “Gene synthesis consortium”

(http://www.genesynthesisconsortium.org/members.php)

A template message how to contact these companies was sent by you per email from Julian last week.

Ela and Silja have ordered the organisms from which we will extract the dockerins from the DSMZ. To work with those, we need to start preparing media. Udhaya has agreed to find a company until the 7^th which will then produce our scaffoldin constructs.

1.) Labwork:

We have formed our first groups for the two scaffoldins as well as the three enzymes. Debby and Alaa will ask around in the Biochemistry Department for concrete ideas for a more complex enzyme systems.

Coming next week, Silja and Elzbieta will show at least one person from each enzyme group, how to extract the dockerines from the organisms. The groups will then each extract a dockerin and prepare the enzymes.

2.) Sponsors:

Sindhu will prepare a letter for Prof. Daniel, which will then also be sent out with each booklet.

The booklets are currently in print; as soon as Avril hears from the printers she will tell us. We will then start sending them out.

On our next meeting, we will finalise our working groups as well as set up minimum working hours for the lab.

1.) Labwork:

We agreed on a minimum work hour per month set at 30 h. Each participant can divide their own time as they wish, as long as at least two persons are present in the lab as well as an additional PhD / Postdoc on the ground floor in case of accidents.

If the minimum work hours aren't kept, the person may be kicked from the team. The hours may be transferred to another person, if both parties agree.

The work groups have been put together.

Each work group will loan their own equipment. The loaning person is responsible for any damages. Any damages will have to be paid by the person who loaned the equipment.

Update: Booklets are printed and will be cut and put into letters on Wednesday.

3.) Sponsors:

Sindhu/Nida have updated Sponsors, however everyone needs to check the addresses and whether they are correct. Sindhu has also started writing a general letter to send to sponsors.

4.) Office:

Julian: Sorted out an office, which is big and most likely free for the entire time of iGem. It is on the 2nd floor of the Geography building. There are two keys, which a system is needed so everyone who needs the office has access.

Attendance

Alaa, Dennis, Julian, Sindhu, Udhaya, Verena and Ela

1.) Money - GZMB

Julian has managed to write a letter for the GZMB to ask for money and let Prof. Dr. Rolf Daniel sign it. Prof. Daniel will send it this afternoon and we should have a response within 2-3 days.

2.) Schedule – overview

Scaffoldins:

Finances needed: Maybe Prof. Daniel will pay for one of the constructs, ordering (2-3 weeks), vector cloning (4-6 weeks). Labwork could therefore start in 4-6 weeks

Dockerins:

Strains have to be ground and DNA isolated, PCR and cloning into pBAD, extraction and purification when fused to enzymes. Lab work can start now.

Enzymes:

Chosen enzymes need to be cloned into pJET (no activity) and then into pBAD with Dockerins. Expression and purification follow afterwards. Labwork can start now.

3.) Working groups

Due to started lab work, exams and practical courses we had to rethink our groups for the moment.

Ela gave us the advice that it would be the best to have (at the moment) 2 groups working on the enzymes (5 enzymes plus GFP), 1 group working on the dockerins and 1 group pushing the sponsors. Without money we cannot register and go on with the project!

Enzyme groups:

1) Avi, Stefani, Joschy

2) Debby, Alaa, Udhaya

Dockerin group:

Julian, Dennis

Sponsor group:

Sindhu, Verena (until the 24^th march, afterwards also free for lab work)

4.) Lab times

We agreed on a minimum work hour per month set at 20 h per person. Due to organisation this month does not count.

5.) Keys

All lab keys and our office key can be found in our own locker. Ask Julian for the numbers of the combination lock!

6.) Time table

We agreed on creating an overall time table that will be uploaded into the Dropbox and updated so that everybody knows exactly what has been done so far in the lab and has to be done in the next days!

7.) Lab equipment lending

At least one person of each group has to come tomorrow 17^th March at 10:30 p.m. to lend lab equipment the groups will need the next weeks.

Missing: Sindhu

1.) Sponsors:

We need to wait 2 weeks until we hear from the GZMB about funding. This means we will have to pay the late fee for iGEM. Any sponsor bills for sponsors we find until then will be held back until we have a thumbs up from the GZMB funding.

Avi will put a new file with sponsors into the Dropbox, to see if everyone can edit it. The list will be updated with additional contacts
Debbie has received two no answers and no other replies.
Julian: No news from Sparkasse, another contact will be updated once he can reach Prof. Stülke
Add more local sponsors
Joschy will call his own sponsors, who haven't replied
Will ask Verena to contact VW again, but without calling it sponsoring (differences in taxation)

2.) Lab updates:

D: growing bacteria is tricky; two of 4 cultures may be growing but are very slow. They were plated on solid medium in order to see if they will grow there. The first media and trace elements didn't work. But have been redone now. The two cultures that have grown so far will also be extracted (tomorrow).
E1: designed primers for esterase and phosphatase in order to fuse it with dockerin and plasmid. The plasmid has a His-tag. Tomorrow they will do the first PCR with the primers for the phosphatase. Will ask Gabrielle about Cycler.
E2: nothing so far.

3.) Website:

Alex, who studies economical informatics, has joined our team and will work on the website and help with the Wiki. Julian will contact Cedric about login for the website. All company logos shall be added to the Dropbox when they are received.
Joschy has been thinking about the webpage: maybe have a picture in the background instead of a plain one.

4.) Other stuff:

Joschy will have a look at the structure or a possible picture for our flexosome once he has the sequences. Binding simulation on pymol.
