Aliphatic (R)-hydroxynitrile lyase

Aliphatic (R)-hydroxynitrile lyase (, (R)-HNL, (R)-oxynitrilase, (R)-hydroxynitrile lyase, LuHNL) is an enzyme with systematic name (2R)-2-hydroxy-2-methylbutanenitrile butan-2-one-lyase (cyanide forming). This enzyme catalyses the following chemical reaction:


 * (2R)-2-hydroxy-2-methylbutanenitrile $$\rightleftharpoons$$ cyanide + butan-2-one

The enzyme contains Zn2+.
