ENZYME entry: EC 2.4.1.85

Accepted Name
cyanohydrin beta-glucosyltransferase.
Alternative Name(s)
UDP-glucose-p-hydroxymandelonitrile glucosyltransferase.
UGT85B1.
uridine diphosphoglucose-cyanohydrin glucosyltransferase.
uridine diphosphoglucose-p-hydroxymandelonitrile glucosyltransferase.
Reaction catalysed
(S)-4-hydroxymandelonitrile + UDP-alpha-D-glucose <=> dhurrin + H(+) + UDP
Comment(s)
  • Acts on a wide range of substrates in vitro, including cyanohydrins, terpenoids, phenolics, hexanol derivatives and plant hormones, in a regiospecific manner.
  • Involved in the biosynthesis of the cyanogenic glucoside dhurrin in sorghum, along with EC 1.14.14.36 and EC 1.14.14.37.
  • This reaction prevents the disocciation and release of toxic hydrogen cyanide.
