pBAD/araC.luxABG.R0011N.luxCDE - bright

Part K1725350 is a reorganised luxABGCDE operon with pBAD promoter upstream luxA and K1725080)promoter upstream luxC generated by BioBrick assembly of pBAD.luxABG-bright (BBa_K1725350)and K1725080.luxCDE-bright (BBa_K1725351).

Design of the RBS library for luxABG

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. We report that the final construct K1725352 (pBAD/araC.luxABG.K1725080.luxCDE) is the brightest that we found out of over 1 billion possible combinations.
