2.4.1.354 |
Accepted name: |
(R)-mandelonitrile β-glucosyltransferase |
Reaction: |
UDP-α-D-glucose + (R)-mandelonitrile = UDP + (R)-prunasin |
Glossary: |
(R)-mandelonitrile = (2R)-hydroxy(phenyl)acetonitrile
(R)-prunasin = (2R)-(β-D-glucosyloxy)(phenyl)acetonitrile |
Other name(s): |
UGT85A19 (gene name) |
Systematic name: |
UDP-α-D-glucose:(R)-mandelonitrile β-D-glucosyltransferase (configuration-inverting) |
Comments: |
The enzyme, characterized from Prunus dulcis (almond), is involved in the biosynthesis of the cyanogenic glycosides (R)-prunasin and (R)-amygdalin. |
