Subcellular Location:
Peroxisome.

Function

Function:
Has 2-hydroxyacid oxidase activity. Most active on the 2-carbon substrate glycolate, but is also active on 2-hydroxy fatty acids, with high activity towards 2-hydroxy palmitate and 2-hydroxy octanoate.
Pathway:
Organic acid metabolism; glycolate degradation; 3-phospho-D-glycerate from glycolate: step 1/4.
Catalytic Activity:
(S)-2-hydroxy acid + O(2) = 2-oxo acid + H(2)O(2).
Cofactor:
COFACTOR: Name=FMN; Xref=ChEBI:CHEBI:58210;
Kinetics:
BIOPHYSICOCHEMICAL PROPERTIES: Kinetic parameters: KM=141 uM for glycolate
Active Site:
ACT_SITE 260 260 Proton acceptor.
