General annotation (Comments)

Function	Has 2-hydroxyacid oxidase activity. Most active on the 2-carbon substrate glycolate, but is also active on 2-hydroxy fatty acids.
Catalytic activity	(S)-2-hydroxy acid + O₂ = 2-oxo acid + H₂O₂.
Cofactor	FMN.
Pathway	Organic acid metabolism; glycolic acid degradation; 3-phospho-D-glyceric acid from glycolic acid: step 1/4.
Subcellular location	Peroxisome.
Tissue specificity	Liver.
Sequence similarities	Belongs to the FMN-dependent alpha-hydroxy acid dehydrogenase family. Contains 1 FMN hydroxy acid dehydrogenase domain.
