E. coli plasmids and strains for biofuel synthesis

Tech ID: T-017688

pA5c-tesA, pA8c-tesA-mleuABCD, pE2k-alsS-ilvCD

Researchers used a standard restriction digestion cloning based on the Biobrick platform or Gibson assembly to construct the plasmids. E. coli DH10B was used for cloning. These plasmids were designed to increase branch chain fatty acid production.

pE8s-fadR, pBARk-tetA-rfp

Researchers used BglBrick and Golden Gate assembly methods to construct the plasmids.

The FFA biosensor plasmid pBARk-rfp contains a FFA-activated PAR promoter 5′ of a red fluorescent protein gene. PAR was replaced by the promoters PAR1, PAR2 and PAR3 (which do not respond to FFA) in plasmids pBAR1k-rfp, pBAR2k-rfp and pBAR3k-rfp, respectively. The FFA biosensor and its controls were evaluated following a previously reported method. A Hill equation was used for data fitting.
