Reaction: UDP-glucose + indoxyl = UDP + indican
Glossary: indoxyl = indole-3-ol
Other name(s): indoxyl-UDPG-glucosyltransferase
Systematic name: UDP-glucose:indoxyl 3-O-β-D-glucosyltransferase
Comments: Also acts to a limited extent on 4-, 5-, 6- and 7-hydroxyindole. After enzymic or chemical hydrolysis, indican forms indoxyl, which, in turn, is converted in the presence of oxygen to the dye indigo.
