Transcription of matR gene in Rhizobium leguminosarum bv. trifolii.
A transcriptional regulator, MatR, encoded on Rhizobium leguminosarum bv. trifolii matR gene was reported to repress mat operon gene expression by binding the upstream operator site. Also, MatR activated its own gene expression by binding the same site that caused the transcriptional repression of the mat operon. This report suggests that MatR plays a dual role in the transcription of matR and matABC with malonate as a positive effector.
