Indole-3-acetate beta-glucosyltransferase (EC 2.4.1.121) is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme characterised from maize are indole-3-acetic acid and UDP-glucose. Its products are 1-O-(indol-3-ylacetyl)-β-D-glucose and uridine diphosphate (UDP). This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:(indol-3-yl)acetate beta-D-glucosyltransferase. Other names in common use include uridine diphosphoglucose-indoleacetate glucosyltransferase, UDPG-indol-3-ylacetyl glucosyl transferase, UDP-glucose:indol-3-ylacetate glucosyltransferase, indol-3-ylacetylglucose synthase, UDP-glucose:indol-3-ylacetate glucosyl-transferase, IAGlu synthase, IAA-glucose synthase, and UDP-glucose:indole-3-acetate beta-D-glucosyltransferase.
