Reaction: UDP-glucose + gallate = UDP + 1-galloyl-β-D-glucose
Other name(s): UDP-glucose—vanillate 1-glucosyltransferase; UDP-glucose:vanillate 1-O-glucosyltransferase; UDP-glucose:gallate glucosyltransferase
Systematic name: UDP-glucose:gallate β-D-glucosyltransferase
Comments: A number of substituted benzoic acids and, more slowly, cinnamic acids, can act as acceptors. Vanillin is the best acceptor investigated.
