Protein

Beta-D-glucopyranosyl abscisate beta-glucosidase

Gene
BGLU18, BG1, BGL1, At1g52400, F19K6.15
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Hydrolyzes abscisic acid glucose ester (ABA-GE) which represents the predominant form of conjugated ABA (biologically inactive). No activity with beta-D-glucopyranosyl zeatin. The hydrolysis of ABA-GE in the endoplasmic reticulum (ER) forms free ABA and contributes to increase its cellular levels under dehydration conditions. ABA-GE hydrolyzing activity is enhanced by dehydration stress-induced polymerization into higher molecular weight forms. The ABA produced by BGLU18 contributes to the initiation of intracellular signaling as well as the increase in the extracellular ABA level.2 Publications

Catalytic activityi

D-glucopyranosyl abscisate + H2O = D-glucose + abscisate.1 Publication

Kineticsi

pH dependencei

Optimum pH is 6.0.
