Protein
(S)-hydroxynitrile lyase
Gene
HNL
Organism
Hevea brasiliensis (Para rubber tree) (Siphonia brasiliensis)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

Involved in cyanogenesis, the release of HCN from injured tissues. Decomposes a varieties of (R) or (S) cyanohydrins into HCN and the corresponding aldehydes and ketones. The natural substrate of this enzyme is (S)-acetone cyanohydrin.

Catalytic activityi

An aliphatic (S)-hydroxynitrile = cyanide + an aliphatic aldehyde or ketone.
An aromatic (S)-hydroxynitrile = cyanide + an aromatic aldehyde.
