                1.1.3.15 (S)-2-hydroxy-acid oxidase
IUBMB Comments
A flavoprotein (FMN). Exists as two major isoenzymes; the A form preferentially oxidizes short-chain aliphatic hydroxy acids, and was previously listed as EC 1.1.3.1, glycolate oxidase; the B form preferentially oxidizes long-chain and aromatic hydroxy acids. The rat isoenzyme B also acts as EC 1.4.3.2, L-amino-acid oxidase.

LITERATURE
structures of recombinant GO complexed with sulfate, glyoxylate, and 4-carboxy-5-dodecylsulfanyl-1,2,3-triazole (CDST), determined by X-ray crystallography are reported. A loop region (loop 4), is completely visible when the GO active site contains a small ligand. Lack of electron density for this loop in the GOCDST complex, mimicking a large substrate, indicates that a disordered to ordered transition occurs with substrate binding. Conformational flexibility of Trp110 is responsible for enabling GO to react with R-hydroxy acids. Movement of Trp110 disrupts a hydrogen-bonding network between Trp110, Leu191, Tyr134, and Tyr208. This loss indicates that active site movements are directly linked to changes in the conformation of loop 4

EXPRESSION
ORGANISM
UNIPROT
LITERATURE
the metabolic gene HAO2 is downregulated in hepatocellular carcinoma. Hao2 downregulation is species- and etiology-independent in humans and rodents
APPLICATION

UNIPROT
COMMENTARY hide
LITERATURE
drug development
in humans the enzyme is a potential drug target for treatment of primary hyperoxaluria, a genetic disorder where overproduction of oxalate results in the formation of kidney stones
diagnostics
the metabolic gene HAO2 is downregulated in hepatocellular carcinoma and predicts metastasis and poor survival. Dysregulation of HAO2 is a very early event in the development of hepatocellular carcinoma and it may represent a useful diagnostic and prognostic marker for human hepatocellular carcinoma
