1 Indole-Induced Activities of beta-Lactamase and Efflux Pump Confer Ampicillin Resistance in Pseudomonas putida KT2440. Ampicillin class C beta-lactamase Pseudomonas putida KT2440
2 Transcriptome, mutant, and inhibitor studies have suggested that Amp resistance induced by indole can be attributed to increased gene expression of ttgAB encoding two genes of RND-type multidrug efflux operons and an ampC encoding beta-lactamase. Ampicillin class C beta-lactamase Pseudomonas putida KT2440
3 Expression, enzyme activities, and mutational analyses indicated that AmpC beta-lactamase is important for acquiring Amp resistance of P. putida in the presence of indole. Ampicillin class C beta-lactamase Pseudomonas putida KT2440
4 Our data indicates that indole reduces Amp-induced heterogeneity by promoting expression of TtgABC or MexAB-OprM efflux pumps and the indole-induced beta-lactamase in P. putida and P. aeruginosa. Ampicillin class C beta-lactamase Pseudomonas putida KT2440
