ENZYME entry: EC 3.2.1.175

Accepted Name
beta-D-glucopyranosyl abscisate beta-glucosidase.
Alternative Name(s)
ABA-beta-D-glucosidase.
beta-D-glucopyranosyl abscisate hydrolase.
Reaction catalysed
(+)-abscisic acid D-glucopyranosyl ester + H2O <=> 2-cis-(+)-abscisate + beta-D-glucose + H(+)
Comment(s)
  • The enzyme hydrolzes the biologically inactive beta-D-glucopyranosyl ester of abscisic acid to produce active abscisate.
  • Abscisate is a phytohormone critical for plant growth, development and adaption to various stress conditions.
  • The enzyme does not hydrolyze beta-D-glucopyranosyl zeatin.
