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.
