Thiophene metabolism by E. coli
The objective of this project is to investigate the mechanism of degradation of sulfur-containing heterocyclic molecules by mutant strains of Escherichia coli K-12. We have previously isolated multiple mutants of E. coli which had gained the capacity to oxidize thiophene compounds and their furan analogs. We have focused on the thdA mutation in our subsequent research, as this appears to be in a regulatory gene central to the thiophene/furan oxidation system. The thdF gene appears to be more directly involved in the oxidation reactions, whereas thdC and thdD are apparently required for increased protection against the toxic effects of thiophene and furan compounds. 4 tabs.
