BadM is a transcriptional repressor and one of three regulators that control benzoyl coenzyme A reductase gene expression in Rhodopseudomonas palustris.
The rate-limiting enzyme of anaerobic benzoate degradation by Rhodopseudomonas palustris, benzoyl coenzyme A (CoA) reductase, is highly sensitive to oxygen, and its synthesis is tightly regulated. We determined that a previously unknown gene in the benzoate gene cluster, badM, encodes a transcriptional repressor of benzoyl-CoA reductase gene expression. BadM controls gene expression from the benzoyl-CoA reductase promoter in concert with two previously described transcriptional activators.
