Abstract
A mutant of Escherichia coli was isolated in which the trimethylamine N-oxide (TMAO) reductase activity is lost and the inducible TMAO reductase protein is absent. The lack of the gene product specifically prevents the expression of torA::lacZ fusion indicating a transcriptional control of torA, the TMAO reductase structural gene. The gene designated torR was mapped at 22 min on the chromosome.Keywords
