CC -!- FUNCTION: Required for the expression of anaerobic nitric oxide (NO)
CC reductase, acts as a transcriptional activator for at least the norVW
CC operon. Activation also requires sigma-54. Not required for induction
CC of the aerobic NO-detoxifying enzyme NO dioxygenase. Binds to the
CC promoter region of norVW, to a consensus target sequence, GT-(N7)-AC,
CC which is highly conserved among proteobacteria.
CC {ECO:0000269|PubMed:11751865, ECO:0000269|PubMed:12586421}.
CC -!- PATHWAY: Nitrogen metabolism; nitric oxide reduction.
CC -!- INDUCTION: By anaerobic conditions, however not induced by NO alone.
CC -!- DOMAIN: Deletion of amino acids 30-164 allows induction of NO reductase
CC activity even in the absence of NO, i.e. the need for an NO-induced
CC signal has been bypassed.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAA69218.1; Type=Frameshift; Evidence={ECO:0000305};
CC Sequence=AAA69219.1; Type=Frameshift; Evidence={ECO:0000305};
CC Sequence=AAA92665.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
