Protein Information (annotations from UniProt)

Database IDHIV0000965
UniProt IDP34913
Primary gene name(s)EPHX2
Synonym gene name(s)unknown
Protein nameBifunctional epoxide hydrolase 2 [Includes: Cytosolic epoxide hydrolase 2
Protein functionBifunctional enzyme. The C-terminal domain has epoxide hydrolase activity and acts on epoxides, alkene oxides, oxiranes and arene oxides. Plays a role in xenobiotic metabolism by degrading potentially toxic epoxides. Also determines steady-state levels of physiological mediators. The N-terminal domain has lipid phosphatase activity, with the highest activity towards threo-9,10-phosphonooxy-hydroxy-octadecanoic acid, followed by erythro-9,10-phosphonooxy-hydroxy-octadecanoic acid, 12-phosphonooxy-octadec-9Z-enoic acid, 12-phosphonooxy-octadec-9E-enoic acid, and p-nitrophenyl phosphate. {ECO:0000269|PubMed:12574508, ECO:0000269|PubMed:12574510}.
