ENZYME entry: EC 4.1.2.46
| Accepted Name |
|---|
| Aliphatic (R)-hydroxynitrile lyase.
|
| Alternative Name(s) |
|---|
| (R)-hydroxynitrile lyase. |
| (R)-oxynitrilase. |
| Reaction catalysed |
|---|
| (2R)-2-hydroxy-2-methylbutanenitrile <=> cyanide + butan-2-one |
| Cofactor(s) |
|---|
| Zn(2+).
|
| Comment(s) |
|---|
- The enzyme catalyzes the stereoselective synthesis of aliphatic (R)-
cyanohydrins.
- No activity toward 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.
- Formerly EC 4.1.2.37 and EC 4.1.2.39.
