Protein
HTH-type transcriptional repressor NanR
Organism
Escherichia coli (strain K12)
Function
Transcriptional repressor that controls expression of the genes required for the catabolism of sialic acids (PubMed:9864311, PubMed:12897000, PubMed:23935044). Represses expression of the nanATEK-yhcH, nanCMS and yjhBC operons. Acts by binding directly to the Nan box, a region of approximately 30 bp covering the promoter region (PubMed:23935044).
Similarity
Belongs to the NanR family.
