Description
In enzymology, a mandelonitrile lyase is an enzyme that catalyzes the chemical reaction:mandelonitrile↔ hydrogen cyanide + benzaldehyde. Hence, this enzyme has one substrate, mandelonitrile, and two products, hydrogen cyanide and benzaldehyde. This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. This enzyme participates in cyanoamino acid metabolism. It has 2 cofactors:flavin, and flavoprotein.
