function:Serine hydrolase that catalyzes the hydrolytic activation of amino acid ester prodrugs of nucleoside analogs such as valacyclovir and valganciclovir. Activates valacyclovir to acyclovir. May play a role in detoxification processes.,similarity:Belongs to the AB hydrolase superfamily. Lipase family.,subunit:Monomer.,tissue specificity:Expressed at high levels in liver and kidney and lower levels in heart, intestine and skeletal muscle.,
