CC -!- FUNCTION: Is involved in NO detoxification in an aerobic process,
CC termed nitric oxide dioxygenase (NOD) reaction that utilizes O(2) and
CC NAD(P)H to convert NO to nitrate, which protects the bacterium from
CC various noxious nitrogen compounds. Therefore, plays a central role in
CC the inducible response to nitrosative stress. {ECO:0000256|HAMAP-
CC Rule:MF_01252}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=NADH + 2 nitric oxide + 2 O2 = H(+) + NAD(+) + 2 nitrate;
CC Xref=Rhea:RHEA:19469, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379,

CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01252};
CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
CC {ECO:0000256|HAMAP-Rule:MF_01252};
CC -!- DOMAIN: Consists of two distinct domains; an N-terminal heme-containing
CC oxygen-binding domain and a C-terminal reductase domain with binding
CC sites for FAD and NAD(P)H. {ECO:0000256|HAMAP-Rule:MF_01252}.
CC -!- SIMILARITY: Belongs to the globin family. Two-domain flavohemoproteins
CC subfamily. {ECO:0000256|ARBA:ARBA00008414, ECO:0000256|HAMAP-
CC Rule:MF_01252}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the flavoprotein
CC pyridine nucleotide cytochrome reductase family.
CC {ECO:0000256|ARBA:ARBA00006401, ECO:0000256|HAMAP-Rule:MF_01252}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01252}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
