K1725080.luxCDE - bright

Part K1725351 is a luxCDE gene assembly under the R0011-N (BBa_K1725080) promoter generated by BioBrick assembly of luxC (BBa_K1725202), luxD (BBa_K1725203) and luxE (BBa_K1725204) ribosome binding site (RBS) libraries.

The assembly has been shown to induce high levels of bioluminescence in E. coli when co-tranformed with pBAD.luxABG-bright (BBa_K1725350). [http://2015.igem.org/Team:Glasgow/Description More information] about the part.

Design of the RBS library for luxCDE

For the construction of the RBS library, a master sequence based on the RBS B0032 was used. 4 nucleotides within the actual ribosome binding site were randomised giving 32 different B0032-derived RBS variants. The predicted efficiency of each RBS library member was estimated using RBS Library Calculator. Originally, RBS Library was designed for every gene in luxABGCDE operon (BBa_K1725352) in order to optimise bioluminescence in E. coli. 32 different BioBrick RBS variants were incorporated upstream of each of the lux genes by PCR, and different libraries were then combined together by BioBrick assembly. This method could potentially produce over 1 billion different variants of the lux operon. Just for the luxCDE assembly, there are over 32000 different variants.
