Class of enzymes
In enzymology, a 3-hydroxy-2-methylpyridinecarboxylate dioxygenase (EC 1.14.12.4) is an enzyme that catalyzes the chemical reaction
3-hydroxy-2-methylpyridine-5-carboxylate + NAD(P)H + H+ + O2 formula_1 2-(acetamidomethylene)succinate + NAD(P)+
The 5 substrates of this enzyme are 3-hydroxy-2-methylpyridine-5-carboxylate, NADH, NADPH, H+, and O2, whereas its 3 products are 2-(acetamidomethylene)succinate, NAD+, and NADP+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with NADH or NADPH as one donor, and incorporation of two atoms of oxygen into the other donor. The systematic name of this enzyme class is 3-hydroxy-2-methylpyridine-5-carboxylate,NAD(P)H:oxygen oxidoreductase (decyclizing). Other names in common use include methylhydroxypyridinecarboxylate oxidase, 2-methyl-3-hydroxypyridine 5-carboxylic acid dioxygenase, methylhydroxypyridine carboxylate dioxygenase, and 3-hydroxy-3-methylpyridinecarboxylate dioxygenase [incorrect]. This enzyme participates in vitamin B6 metabolism. It employs one cofactor, FAD.
