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. {ECO:0000255|HAMAP-
CC       Rule:MF_01314}.
CC   -!- PATHWAY: Nitrogen metabolism; nitric oxide reduction.
CC       {ECO:0000255|HAMAP-Rule:MF_01314}.
