Beta-glucosidase involved in the rapid degradation of flavonol 3-O-beta-glucoside-7-O-alpha-rhamnosides during abiotic stress recovery. No activity with quercetin 3-O-alpha-rhamnoside, quercetin 3-O-beta-galactoside and rutin. Hydrolysis of terminal, non-reducing beta-D-glucosyl residues with release of beta-D-glucose. kcat is 1.30 sec(-1) with kaempferol 3-O-beta-glucoside-7-O-alpha-rhamnoside as substrate. kcat is 1.10 sec(-1) with quercetin 3-O-beta-glucoside-7-O-alpha-rhamnoside as substrate. kcat is 0.92 sec(-1) with kaempferol 3-O-beta-glucoside as substrate. kcat is 0.57 sec(-1) with quercetin 3-O-beta-glucoside as substrate. kcat is 4.08 sec(-1) with p-nitrophenyl beta-D-glucoside as substrate. Optimum pH is 5.0. Up-regulated during abiotic stress recovery. Belongs to the glycosyl hydrolase 1 family. Sequencing errors.
