CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+) + NAD(+) + 2 reduced [nitric oxide reductase rubredoxin
CC         domain] = NADH + 2 oxidized [nitric oxide reductase rubredoxin
CC         domain]; Xref=Rhea:RHEA:42960, Rhea:RHEA-COMP:10304, Rhea:RHEA-

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01313};
CC   -!- PATHWAY: Nitrogen metabolism; nitric oxide reduction.
CC       {ECO:0000255|HAMAP-Rule:MF_01313}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01313}.
CC   -!- SIMILARITY: Belongs to the FAD-dependent oxidoreductase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01313}.
