IUBMB Enzyme Nomenclature


Accepted name: cytokinin 7-β-glucosyltransferase

Reaction: UDP-glucose + an N6-alkylaminopurine = UDP + an N6-alkylaminopurine-7-β-D-glucoside

zeatin = (E)-2-methyl-4-(9H-purin-6-ylamino)but-2-en-1-ol = (E)-N6-(4-hydroxy-3-methylbut-2-enyl)adenine

Other name(s): uridine diphosphoglucose-zeatin 7-glucosyltransferase; cytokinin 7-glucosyltransferase; UDP-glucose:zeatin 7-glucosyltransferase

Systematic name: UDP-glucose:N6-alkylaminopurine 7-glucosyltransferase

Comments: Acts on a range of N6-substituted adenines, including zeatin and N6-benzylaminopurine, but not N6-benzyladenine. With some acceptors, 9-β-D-glucosides are also formed.
