Organism

Erwinia carotovora subsp. atroseptica (Pectobacterium atrosepticum) [Complete proteome] [HAMAP]

Taxonomic identifier

29471 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Pectobacterium

Protein attributes

Sequence length	396 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. 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.
