Accepted name: |
abscisate β-glucosyltransferase |
Reaction: |
UDP-α-D-glucose + abscisate = UDP + β-D-glucopyranosyl abscisate |

Other name(s): |
ABA-glucosyltransferase; ABA-GTase; AOG; UDP-D-glucose:abscisate β-D-glucosyltransferase |
Systematic name: |
UDP-α-D-glucose:abscisate β-D-glucosyltransferase (configuration-inverting) |
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. |
