(S)-hydroxynitrile lyase.
based on mapping to UniProt P52704
(1) An aliphatic (S)-hydroxynitrile = cyanide + an aliphatic aldehyde or ketone. (2) An aromatic (S)-hydroxynitrile = cyanide + an aromatic aldehyde.
-!- 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.
