In enzymology, a (S)-2-hydroxy-acid oxidase (EC 1.1.3.15) is an enzyme that catalyzes the chemical reaction
- (S)-2-hydroxy acid + O2 2-oxo acid + H2O2
Thus, the two substrates of this enzyme are (S)-2-hydroxy acid and O2, whereas its two products are 2-oxo acid and H2O2.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. The systematic name of this enzyme class is (S)-2-hydroxy-acid:oxygen 2-oxidoreductase. Other names in common use include glycolate oxidase, hydroxy-acid oxidase A, hydroxy-acid oxidase B, glycolate oxidase, oxidase, L-2-hydroxy acid, hydroxyacid oxidase A, L-alpha-hydroxy acid oxidase, and L-2-hydroxy acid oxidase. This enzyme participates in glyoxylate and dicarboxylate metabolism. It employs one cofactor, FMN.
Structural studies[edit]
As of late 2007, 5 structures have been solved for this class of enzymes, with PDB accession codes 1AL7, 1AL8, 1GYL, 1TB3, and 2NZL.
