Chains	Enzyme Name	Description	Catalytic Residues
A	(S)-2-hydroxy-acid oxidase M-CSA #852	Glycolate oxidase is a flavoenzyme, which contains a permanently bound FNN cofactor. It catalyses the oxidation of (S)-2-hydroxy-acid to 2-oxo acid. In green plants, glycolate oxidase is one of the key enzymes in photorespiration where it oxidizes glycolate to glyoxylate. Comparison of properties with the extensively studied L-lactate oxidase and the topography of the active site and the amino acids surrounding the prosthetic group FMN led to the proposal of a reaction mechanism.
