In enzymology, a beta-primeverosidase (EC 3.2.1.149) is an enzyme that catalyzes the chemical reaction
- a 6-O-(beta-D-xylopyranosyl)-beta-D-glucopyranoside + H2O 6-O-(beta-D-xylopyranosyl)-beta-D-glucopyranose + an alcohol
Thus, the two substrates of this enzyme are 6-O-(beta-D-xylopyranosyl)-beta-D-glucopyranoside and H2O, whereas its two products are 6-O-(beta-D-xylopyranosyl)-beta-D-glucopyranose and alcohol.
This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is 6-O-(beta-D-xylopyranosyl)-beta-D-glucopyranoside 6-O-(beta-D-xylosyl)-beta-D-glucohydrolase.
