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.
