The favorite pets of a synthetic biologist
Escherichia coli
We used the following E. coli strains during our project:
- KRX (Source: Promega)
- Genotype: [F´, traD36, ΔompP, proA+B+, lacIq, Δ(lacZ)M15] ΔompT, endA1, recA1, gyrA96 (Nalr), thi-1, hsdR17 (rk–, mk+), e14– (McrA–), relA1, supE44, Δ(lac-proAB), Δ(rhaBAD)::T7 RNA polymerase.
- ER2566 (T7 Express Competent E. coli (High Efficiency), source: New England Biolabs)
- Genotype: F- λ- fhuA2 [lon] ompT lacZ::T7 gene 1 gal sulA11 Δ(mcrC-mrr)114::IS10 R(mcr-73::miniTn10-TetS)2 R(zgb-210::Tn10)(TetS) endA1 [dcm]
Some other strains were used just once to investigate their performance in in vitro cell-free protein synthesis:
- Rosetta-gami 2 (Source: Novagen, part of Merck KGaA)
- Genotype: Δ(ara-leu)7697 ΔlacX74 ΔphoA PvuII phoR araD139 ahpC galE galK rpsL F′[lac+ lacIq pro] gor522::Tn10 trxB pRARE2 (CamR, StrR, TetR)
- BL21 (DE3) (Source: New England Biolabs)
- Genotype: fhuA2 [lon] ompT gal (λ DE3) [dcm] ∆hsdS λ DE3 = λ sBamHIo ∆EcoRI-B int::(lacI::PlacUV5::T7 gene1) i21 ∆nin5
Bacillus subtilis
In our project we used B. subtilis strain 168 with genotype trpC2 for the GABA operon sequence. You can find further information about the origin of this strain in Zeigler et al.
Agrobacterium tumefaciens
We isolated the blc-operon from A. tumefaciens C58.1. For detailed information about this organism please be referred to Wood et al. 2001.
