Sysname
UDP-glucose:7,8-dihydroxycoumarin 7-O-beta-D-glucosyltransferase
Reaction(IUBMB)
UDP-glucose + 7,8-dihydroxycoumarin = UDP + daphnin [RN:R03548]
Reaction(KEGG)
Substrate
UDP-glucose [CPD:C00029];
7,8-dihydroxycoumarin [CPD:C03093]
Product
UDP [CPD:C00015];
daphnin [CPD:C01421]
Comment
Converts the aglycone daphetin into daphnin and, more slowly, esculetin into cichoriin, umbelliferone into skimmin, hydrangetin into hydrangin and scopoletin into scopolin.
