| Function |
A probable transcription regulator, probably involved in carbon metabolism. Binds and probably regulates expression of bidirectional hydrogenase (hoxEFUHY), probably activates its transcription. A possible regulator of redox-responsive genes. Binds 2 direct repeats of the DNA with sequence 5'-CTA-N(9)-CTA-3' in the upstream region of both its own gene (includes the transcription start site) and crhR (includes the initiation codon) in a sequence-specific manner; does not bind crhR RNA. Binds to the crhR gene, represses its transcription.
