Protein

(R)-mandelonitrile lyase 1

Gene

MDL1

Organism
Prunus serotina (Black cherry)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Involved in cyanogenesis, the release of HCN from injured tissues. Catalyzes the stereospecific addition of HCN to a variety of aldehydes in vitro. It is a major seed constituent, and could have the additional role of a storage form for reduced nitrogen.

Catalytic activityi

(R)-mandelonitrile = cyanide + benzaldehyde.

Cofactori

FAD.
