Reaction: UDP-glucose + an hydroxyanthraquinone = UDP + a glucosyloxyanthraquinone
Other name(s): uridine diphosphoglucose-anthraquinone glucosyltransferase; anthraquinone-specific glucosyltransferase
Systematic name: UDP-glucose:hydroxyanthraquinone O-glucosyltransferase
Comments: A range of anthraquinones and some flavones can act as acceptors; best substrates are emodin, anthrapurpurin, quinizarin, 2,6-dihydroxyanthraquinone and 1,8-dihydroxyanthraquinone.
