nrdR | nusB | b0413 | b0416 | Nrd regulon repressor; Represses transcription of the class Ib RNR genes nrdHIEF but has much smaller effect on transcription of the class Ia RNR genes nrdAB and class III RNR genes nrdDG. By binding to nrdR boxes in the promoter regions to alter promoter activity, nrdR differentially regulates nrdAB, nrdHIEF and nrdD transcription in aerobic growth. | Transcription antitermination protein; Involved in transcription antitermination. Required for transcription of ribosomal RNA (rRNA) genes. Binds specifically to the boxA antiterminator sequence of the ribosomal RNA (rrn) operons. The affinity of NusB for the boxA RNA sequence is significantly increased in the presence of the ribosomal protein S10.
