ENZYME entry: EC 4.1.2.47

PURL: https://purl.expasy.org/enzyme/EC/4.1.2.47
Accepted Name
(S)-hydroxynitrile lyase
Alternative Name(s)
(S)-cyanohydrin producing hydroxynitrile lyase
(S)-oxynitrilase
hydroxynitrile lyase
oxynitrilase
Reaction catalysed
  • a monosubstituted aliphatic (S)-hydroxynitrile = an aldehyde + hydrogen cyanide
  • a disubstituted aliphatic (S)-hydroxynitrile = a ketone + hydrogen cyanide
  • an aromatic (S)-hydroxynitrile = an aromatic aldehyde + hydrogen cyanide
Comment(s)
  • Hydroxynitrile lyases catalyzes the the cleavage of hydroxynitriles into cyanide and the corresponding aldehyde or ketone.
  • In nature the liberation of cyanide serves as a defense mechanism against herbivores and microbial attack in plants.
  • In vitro the enzymes from Manihot esculenta and Hevea brasiliensis accept a broad range of aliphatic and aromatic carbonyl compounds as substrates and catalyze the formation of (S)-hydroxynitriles.
  • Formerly EC 4.1.2.37 and EC 4.1.2.39.
