IUBMB Comments
Hydroxynitrile lyases catalyses 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 catalyse the formation of (S)-hydroxynitriles [1,10].
