Expression of the argF gene of Pseudomonas aeruginosa in Pseudomonas aeruginosa, Pseudomonas putida, and Escherichia coli.

R' plasmids carrying argF genes from Pseudomonas aeruginosa strains PAO and PAC were transferred to Pseudomonas putida argF and Escherichia coli argF strains. Expression in P. putida was similar to that in P. aeruginosa and was repressed by exogenous arginine. Expression in E. coli was 2 to 4% of that in P. aeruginosa. Exogenous arginine had no effect, and there were no significant differences between argR' and argR strains of E. coli in this respect.
