IUBMB Enzyme Nomenclature


Accepted name: o-dihydroxycoumarin 7-O-glucosyltransferase

Reaction: UDP-glucose + 7,8-dihydroxycoumarin = UDP + daphnin

Other name(s): uridine diphosphoglucose-o-dihydroxycoumarin 7-O-glucosyltransferase; UDP-glucose:o-dihydroxycoumarin glucosyltransferase

Systematic name: UDP-glucose:7,8-dihydroxycoumarin 7-O-β-D-glucosyltransferase

Comments: Converts the aglycone daphetin into daphnin and, more slowly, esculetin into cichoriin, umbelliferone into skimmin, hydrangetin into hydrangin and scopoletin into scopolin.
