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:0000255|HAMAP-
CC       Rule:MF_01252}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 nitric oxide + NADPH + 2 O2 = 2 nitrate + NADP(+) + H(+);

CC         Rule:MF_01252};
CC       Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.

CC       Note=Binds 1 FAD per subunit. {ECO:0000255|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.
CC   -!- SIMILARITY: Belongs to the globin family. Two-domain flavohemoproteins
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01252}.
CC   -!- SIMILARITY: In the C-terminal section; belongs to the flavoprotein
CC       pyridine nucleotide cytochrome reductase family. {ECO:0000255|HAMAP-
CC       Rule:MF_01252}.
