Trichloroethylene degradation by Escherichia coli containing the cloned Pseudomonas putida F1 toluene dioxygenase genes.
Toluene dioxygenase from Pseudomonas putida F1 has been implicated as an enzyme capable of degrading trichloroethylene. This has now been confirmed with Escherichia coli JM109(pDTG601) that contains the structural genes (todC1C2BA) of toluene dioxygenase under the control of the tac promoter. The extent of trichloroethylene degradation by the recombinant organism depended on the cell concentrat...
متن کاملDegradation of trichloroethylene by toluene dioxygenase in whole-cell studies with Pseudomonas putida F1.
Toluene-induced cells of Pseudomonas putida F1 removed trichloroethylene from growth media at a significantly greater initial rate than the methanotroph Methylosinus trichosporium OB3b. With toluene-induced P. putida F1, the initial degradation rate varied linearly with trichloroethylene concentration over the range of 8 to 80 microM (1.05 to 10.5 ppm). At 80 microM (10.5 ppm) trichloroethylene...
متن کاملToluene degradation by Pseudomonas putida F1. Nucleotide sequence of the todC1C2BADE genes and their expression in Escherichia coli.
The nucleotide sequence of the todC1C2BADE genes which encode the first three enzymes in the catabolism of toluene by Pseudomonas putida F1 was determined. The genes encode the three components of the toluene dioxygenase enzyme system: reductaseTOL (todA), ferredoxinTOL (todB), and the two subunits of the terminal dioxygenase (todC1C2); (+)-cis-(1S, 2R)-dihydroxy-3-methylcyclohexa-3,5-diene deh...
متن کاملGenetic and molecular organization of the alkylbenzene catabolism operon in the psychrotrophic strain Pseudomonas putida 01G3.
The 11-kb sequence encompassing the alkylbenzene upper pathway in Pseudomonas putida 01G3, a psychrotrophic strain able to degrade alkylbenzenes at low temperatures, was characterized. Together with a potential regulator (EbdR), six putative enzymes (EbdAaAbAcAdBC) were identified, and they exhibited highly significant similarities with enzymes implicated in the equivalent pathway in P. putida ...
