Protein
HTH-type transcriptional repressor CsqR
Organism
Escherichia coli (strain K12)
Function
Involved in the regulation of the sulfoquinovose operon (PubMed:24463506, PubMed:30372406). Represses the expression of the yihUTS operon and of the yihV and csqR genes. Binds DNA inside the spacer between the bidirectional transcription units comprising the yihUTS operon and the yihV gene, and upstream the csqR gene itself (PubMed:30372406).
