We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Function

HAOX1_HUMAN 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.

Publication Abstract from PubMed

Glycolate oxidase, a peroxisomal flavoenzyme, generates glyoxylate at the expense of oxygen. When the normal metabolism of glyoxylate is impaired by the mutations that are responsible for the genetic diseases hyperoxaluria types 1 and 2, glyoxylate yields oxalate, which forms insoluble calcium deposits, particularly in the kidneys. Glycolate oxidase could thus be an interesting therapeutic target. The crystal structure of human glycolate oxidase (hGOX) in complex with 4-carboxy-5-[(4-chlorophenyl)sulfanyl]-1,2,3-thiadiazole (CCPST) has been determined at 2.8 A resolution. The inhibitor heteroatoms interact with five active-site residues that have been implicated in catalysis in homologous flavodehydrogenases of L-2-hydroxy acids. In addition, the chlorophenyl substituent is surrounded by nonconserved hydrophobic residues. The present study highlights the role of mobility in ligand binding by glycolate oxidase. In addition, it pinpoints several structural differences between members of the highly conserved family of flavodehydrogenases of L-2-hydroxy acids.
