IUBMB Comments
The enzyme contains Zn2+ . The enzyme catalyses the stereoselective synthesis of aliphatic (R)-cyanohydrins . No activity towards mandelonitrile and 4-hydroxymandelonitrile . Natural substrates for the (R)-oxynitrilase from Linum usitatissimum are acetone and butan-2-one, which are the building blocks of the cyanogen glycosides in Linum, linamarin and lotaustralin, or linustatin and neolinustatin, respectively .
