In enzymology, a hyponitrite reductase is an enzyme that catalyzes the oxidation of hydroxylamine H
2NOH by the nicotinamide adenine dinucleotide cation (NAD+) into hyponitrous acid HON=NOH:

2 H
2NOH + 2 NAD+ HON=NOH + 2 NADH + 2 H+

This systematic name of this enzyme class hydroxylamine:NAD+ oxidoreductase. It is also called NADH2:hyponitrite oxidoreductase.

This enzyme belongs to the family of oxidoreductases, specifically those acting on other nitrogenous compounds as donors with NAD+ or NADP+ as acceptor. It employs one cofactor, metal.

In biochemistry, an oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule, the reductant, also called the electron donor, to another, the oxidant, also called the electron acceptor. This group of enzymes usually utilizes NADP+ or NAD+ as cofactors. Transmembrane oxidoreductases create electron transport chains in bacteria, chloroplasts and mitochondria, including respiratory complexes I, II and III. Some others can associate with biological membranes as peripheral membrane proteins or be anchored to the membranes through a single transmembrane helix.

Hyponitrous acid is a chemical compound with formula H
2N
2O
2 or HON=NOH. It is an isomer of nitramide, H2N−NO2; and a formal dimer of azanone, HNO.
