Up-promoter mutations in the trpBA operon of Pseudomonas aeruginosa.

Journal of bacteriology - 1 Jun 1991

Han C Y, Crawford I P, Harwood C S

Abstract excerpt

In Pseudomonas aeruginosa, the operon encoding tryptophan synthase (trpBA) is positively regulated by the TrpI protein and an intermediate in tryptophan biosynthesis, indoleglycerol phosphate (InGP). A gene fusion in which the trpBA promoter directs expression of the Pseudomonas putida xylE gene was constructed. By using a P. putida F1 todE mutant carrying this fusion on a plasmid, three cis-acting mutations that...
