IUBMB Enzyme Nomenclature


Accepted name: hydroquinone glucosyltransferase

Reaction: UDP-glucose + hydroquinone = UDP + hydroquinone-O-β-D-glucopyranoside

Other name(s): arbutin synthase; hydroquinone:O-glucosyltransferase

Systematic name: UDP-glucose:hydroquinone-O-β-D-glucosyltransferase

Comments: Hydroquinone is the most effective acceptor, but over 40 phenolic compounds are also glucosylated, but at lower rates.
