UniProtKB - P9WMI5 (SMTB_MYCTU)
Protein
HTH-type transcriptional repressor SmtB
Gene
smtB
Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Status
Functioni
Transcriptional regulator involved in zinc homeostasis. Represses the expression of the smtB-zur operon in the absence of zinc. Could act as the metal sensor that controls the expression of zur in response to zinc availability.1 Publication
Activity regulationi
Binding to DNA is inhibited by zinc ions.1 Publication
