BRITE hierarchy
Sysname
UDP-glucose:trans-zeatin O-beta-D-glucosyltransferase
Reaction(IUBMB)
UDP-glucose + trans-zeatin = UDP + O-beta-D-glucosyl-trans-zeatin [RN:R02118]
Reaction(KEGG)
Substrate
UDP-glucose [CPD:C00029];
trans-zeatin [CPD:C00371]
Product
UDP [CPD:C00015];
O-beta-D-glucosyl-trans-zeatin [CPD:C03423]
Comment
Unlike EC 2.4.1.215, cis-zeatin O-beta-D-glucosyltransferase, UDP-D-xylose can also act as donor (cf. EC 2.4.2.40, zeatin O-beta-D-xylosyltransferase).
