transcriptional regulator [Escherichia coli O157:H7 str. Sakai]

Protein Classification

helix-turn-helix domain-containing protein; LacI family DNA-binding transcriptional regulator( domain architecture ID 10013493)

helix-turn-helix (HTH) domain-containing protein with an XRE (Xenobiotic Response Element) family; HTH domain binds DNA and may function as a transcriptional regulator| LacI family DNA-binding transcriptional regulator functions as an activator or repressor by binding a specific effector ligand that either decreases (induction) or increases DNA-binding affinity (co-repression)
