General annotation (Comments)

Function	Is involved in NO detoxification in an aerobic process, termed nitric oxide dioxygenase (NOD) reaction that utilizes O₂ and NAD(P)H to convert NO to nitrate, which protects the bacterium from various noxious nitrogen compounds. Therefore, plays a central role in the inducible response to nitrosative stress By similarity. HAMAP MF_01252
Catalytic activity	2 NO + 2 O₂ + NAD(P)H = 2 NO₃^- + NAD(P)⁺. HAMAP MF_01252
Cofactor	Binds 1 heme B (iron-protoporphyrin IX) group per subunit By similarity. HAMAP MF_01252 Binds 1 FAD per subunit By similarity. HAMAP MF_01252
Domain	Consists of two distinct domains; an N-terminal heme-containing oxygen-binding domain and a C-terminal reductase domain with binding sites for FAD and NAD(P)H. HAMAP MF_01252
Sequence similarities	Belongs to the globin family. Two-domain flavohemoproteins subfamily. In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family. Contains 1 FAD-binding FR-type domain.
