EC 3.2.1.175 Details
EC number
3.2.1.175
Accepted name
β-D-glucopyranosyl abscisate β-glucosidase
Reaction
D-glucopyranosyl abscisate + H2O = D-glucose + abscisate
Other name(s)
AtBG1,
ABA-β-D-glucosidase,
ABA-specific β-glucosidase,
ABA-GE hydrolase,
β-D-glucopyranosyl abscisate hydrolase
Systematic name
β-D-glucopyranosyl abscisate glucohydrolase
Comment
The enzyme hydrolzes the biologically inactive β-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 hydrolyse β-D-glucopyranosyl zeatin [1].
