Accepted name: cis-zeatin O-β-D-glucosyltransferase
Reaction: UDP-glucose + cis-zeatin = UDP + O-β-D-glucosyl-cis-zeatin
Glossary: zeatin = (E)-2-methyl-4-(9H-purin-6-ylamino)but-2-en-1-ol = (E)-N6-(4-hydroxy-3-methylbut-2-enyl)adenine
Systematic name: UDP-glucose:cis-zeatin O-β-D-glucosyltransferase
Comments: The enzyme from maize can use cis-zeatin and UDP-glucose as substrates, but not cis-ribosylzeatin, trans-zeatin or trans-ribosylzeatin. Unlike EC, trans-zeatin O-β-D-glucosyltransferase, UDP-D-xylose cannot act as a donor.
