IUBMB Enzyme Nomenclature


Accepted name: abscisate β-glucosyltransferase

Reaction: UDP-D-glucose + abscisate = UDP + β-D-glucopyranosyl abscisate

Other name(s): ABA-glucosyltransferase; ABA-GTase; AOG

Systematic name: UDP-D-glucose:abscisate β-D-glucosyltransferase

Comments: The enzyme acts better on (S)-2-trans-abscisate than the natural (S)-2-cis isomer, abscisate, or its enantiomer, the (R)-2-cis isomer.
