pFrmR+FrmRAB - An operon that degrades formaldehyde

Basic Description

PfrmR is found upstream of the frmRAB formaldehyde detoxification operon. FrmR, the first product of the operon, is a member of the DUF156 family of DNA-binding transcriptional regulators. It binds the frmRAB promoter region and is negatively allosterically modulated by formaldehyde. FrmR is specific to formaldehyde. The genes frmA and frmB encode a formaldehyde dehydrogenase and S-formylglutathione hydrolase, respectively, and are responsible for detoxifying formaldehyde to formic acid in a glutathione-dependent pathway. The negative-feedback regulation of the frmRAB operon is similar to that of many other prokaryotic operons, whereby the transcription factor represses its own transcription.
