EC | 3.2.1.149 | ||||
Accepted name: | β-primeverosidase | ||||
Reaction: | a 6-O-(β-D-xylopyranosyl)-β-D-glucopyranoside + H2O = 6-O-(β-D-xylopyranosyl)-β-D-glucopyranose + an alcohol | ||||
Glossary: | primeverose = 6-O-(β-D-xylopyranosyl)-D-glucose vicianose = 6-O-(α-L-arabinopyranosyl)-D-glucose |
||||
Systematic name: | 6-O-(β-D-xylopyranosyl)-β-D-glucopyranoside 6-O-(β-D-xylosyl)-β-D-glucohydrolase | ||||
Comments: | The enzyme is responsible for the formation of the alcoholic aroma in oolong and black tea. In addition to β-primeverosides [i.e. 6-O-(β-D-xylopyranosyl)-β-D-glucopyranosides], it also hydrolyses 6-O-(β-D-apiofuranosyl)-β-D-glucopyranosides and, less rapidly, β-vicianosides and 6-O-(α-L-arabinofuranosyl)-β-D-glucopyranosides, but not β-glucosides. Geranyl-, linaloyl-, benzyl- and p-nitrophenol glycosides are all hydrolysed. | ||||
