Protein attributes
| Sequence length | 397 AA. |
| Sequence status | Complete. |
| Protein existence | Inferred from homology. |
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. |
