<h1> Experiments </h1>
 
<h2> 1. Obtaining the genes </h2>
 
  
<p>The first project part pursues the goal to get or clone all genes that are involved in our project into a plasmid, which allows a rapid and easy amplification of those genes for further experiments. </br>
 
For the soluble methane monooxygenase (sMMO) from <i>Methylococcus capsulatus</i> (Bath) we got the genes for the subunits (<i>mmoXYZBCD</i>) cloned into the BioBrick standard vector pSC1B3 from the

iGEM 2014 team from Braunschweig, Germany.

Those six parts are registered as BioBrick parts under the names; Bba_K1390001 (<i>mmoB</i>), Bba_K1390002 (<i>mmoC</i>), Bba_K1390003 (<i>mmoD</i>), Bba_K1390004 (<i>mmoX</i>), Bba_K1390005 (<i>mmoY</i>), and Bba_K1390006 (<i>mmoZ</i>). </br>
 
Genes encoding the enzymes for the conversion of methanol into biomass (<i>medh2</i>, <i>hps</i>, and <i>phi</i>) were amplified by PCR from <i>Bacillus methanolicus</i> (MGA3) genomic DNA and TOPO blunt end cloning into the pCR4 vector was performed. Primers were designed in a way that they bind in the 5’ and 3’ untranslated region (UTR) of each gene.</br>
 
TOPO blunt end cloning of <i>mmoG</i> did not succeed. Instead <i>mmoG</i> was synthesized by IDT as a gBlock gene fragment, codon optimized for protein expression in <i>E. coli</i>.
 
</p>
 
  
<h2> 2. Construction of BioBrick parts</h2>
 
 
<p>The second project part had the intention to create four new basic BioBrick parts. Those basic parts consist of the coding sequences (CDS) of a gene. The codonoptimized <i>mmoG</i> as well as all three genes encoding the enzymes for the methanol to biomass conversion (<i>medh2</i>, <i>hps</i>, and <i>phi</i>) were created as

BioBrick parts.
 
</a> </br>
 
 
The CDS of the <i>hps</i> gene, encoding the 3-hexulose-6-phosphate synthase, contains PstI and XbaI restriction sites making it not compatible with the BioBrick system. In two rounds of <i>in vitro</i> mutagenesis both restriction sites were removed and <i>hps</i> was cloned into pSC1B3 and submitted as a

BioBrick part.
 
</a>
 
</p>
 
 
<h2>3. Generation of expression constructs</h2>
 
 
<p>Before assembling the final constructs we wanted to show that each individual protein could be expressed in <i>E. coli</i>. The pET system has been chosen as our preferred system for overexpression of each individual protein. The vector backbones pET-28 and pET-30 were chosen as potential expression vector.</br>

Figure about construct: T7 prom—RBS—GENE Coming soon
 
</br>
 
</br>
 
With PCR we added restriction enzyme sites at the 5’ and 3’ end of CDS of each gene. Afterwards the gene was cloned either into pET-30 or pET-28 with the use of the listed restriction enzymes (Table 1 coming soon).
