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. Ref.6 Ref.10 Ref.12 Ref.14 Ref.16 Ref.17 Ref.18 Ref.20 Ref.21 Ref.22 Ref.25 Ref.30 Ref.33 Ref.34

In the presence of oxygen and NADH, HMP has NADH oxidase activity, which leads to the generation of superoxide and H2O2, both in vitro and in vivo, and it has been suggested that HMP might act as an amplifier of superoxide stress. Under anaerobic conditions, HMP also exhibits nitric oxide reductase and FAD reductase activities. However, all these reactions are much lower than NOD activity. Ref.6 Ref.10 Ref.12 Ref.14 Ref.16 Ref.17 Ref.18 Ref.20 Ref.21 Ref.22 Ref.25 Ref.30 Ref.33 Ref.34

Various electron acceptors are also reduced by HMP in vitro, including dihydropterine, ferrisiderophores, ferric citrate, cytochrome c, nitrite, S-nitrosoglutathione, and alkylhydroperoxides. However, it is unknown if these reactions are of any biological significance in vivo. Ref.6 Ref.10 Ref.12 Ref.14 Ref.16 Ref.17 Ref.18 Ref.20 Ref.21 Ref.22 Ref.25 Ref.30 Ref.33 Ref.34

Catalytic activity

2 NO + 2 O2 + NAD(P)H = 2 NO3- + NAD(P)+. Ref.30

Cofactor

Binds 1 FAD per subunit. HAMAP MF_01252

Binds 1 heme B group per subunit. HAMAP MF_01252

Subunit structure

Monomer. HAMAP MF_01252

Subcellular location

Cytoplasm. Note: Has also been found to localize into the periplasm, but spectral analysis revealed that biochemically active HMP is exclusively found in the cytoplasmic fraction. Ref.11

Induction

By nitric oxyde NO (under aerobic conditions), nitrite, nitrate (under anaerobic conditions), nitroso compounds, and paraquat. 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. Ref.34

Miscellaneous

No protein-heme interactions have been detected at the distal side of the heme molecule. HAMAP MF_01252

HMP is able to bind specifically unsaturated and/or cyclopropanated fatty acids with high affinity. 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.
