ENZYME entry: EC 3.2.1.149
| Accepted Name |
|---|
| Beta-primeverosidase.
|
| Reaction catalysed |
|---|
| A 6-O-(beta-D-xylopyranosyl)-beta-D-glucopyranoside + H(2)O <=> 6-O-(beta-D-xylopyranosyl)-beta-D-glucopyranose + an alcohol |
| Comment(s) |
|---|
- The enzyme is responsible for the formation of the alcoholic aroma in
oolong and black tea.
- In addition to beta-primeverosides (i.e. 6-O-(beta-D-xylopyranosyl)-
beta-D-glucopyranosides), it also hydrolyzes 6-O-(beta-D-
apiofuranosyl)-beta-D-glucopyranosides and, less rapidly, beta-
vicianosides and 6-O-(alpha-L-arabinofuranosyl)-beta-D-
glucopyranosides, but not beta-glucosides.
- Geranyl-, linaloyl-, benzyl- and p-nitrophenol glycosides are all
hydrolyzed.
