Accepted name: mycophenolic acid acyl-glucuronide esterase

Reaction: mycophenolic acid O-acyl-glucuronide + H2O = mycophenolate + D-glucuronate

Glossary: mycophenolate = (4E)-6-(4-hydroxy-6-methoxy-7-methyl-3-oxo-1,3-dihydro-2-benzofuran-5-yl)-4-methylhex-4-enoate
mycophenolic acid O-acyl-glucuronide = 1-O-[(4E)-6-(4-hydroxy-6-methoxy-7-methyl-3-oxo-1,3-dihydro-2-benzofuran-5-yl)-4-methylhex-4-enoyl]-β-D-glucopyranuronic acid

Other name(s): mycophenolic acid acyl-glucuronide deglucuronidase; AcMPAG deglucuronidase

Systematic name: mycophenolic acid O-acyl-glucuronide-ester hydrolase

Comments: This liver enzyme deglucuronidates mycophenolic acid O-acyl-glucuronide, a metabolite of the immunosuppressant drug mycophenolate that is thought to be immunotoxic.
