cytokinin 7-beta-glucosyltransferase
Ec Number:	2.4.1.118
Cas Number:	72103-03-8
Go Code:	0047807

In enzymology, a cytokinin 7-β-glucosyltransferase is an enzyme that catalyzes the chemical reaction

UDP-glucose + N⁶-alkylaminopurine

\rightleftharpoons UDP + N⁶-alkylaminopurine-7-β-D-glucoside

Thus, the two substrates of this enzyme are UDP-glucose and N⁶-alkylaminopurine, whereas its two products are UDP and N⁶-alkylaminopurine-7-β-D-glucoside.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:N⁶-alkylaminopurine 7-glucosyltransferase. Other names in common use include uridine diphosphoglucose-zeatin 7-glucosyltransferase, and cytokinin 7-glucosyltransferase.
