Abstract
An enzymatic method for the production of an L-glufosinate P-alkyl ester can be performed. This method is characterized by reacting an L-glufosinate P-alkyl ester carbamoylate to give the corresponding L-glufosinate P-alkyl ester. This is catalyzed by a carbamoylase. The L-glufosinate P-alkyl ester carbamoylate employed may be obtained by a reaction from the corresponding L-glufosinate hydantoin P-alkyl ester. This is catalyzed by a hydantoinase, preferably an L-enantioselective hydantoinase. In a second aspect, an enzymatic method for enantioselective production of an L-glufosinate P-alkyl ester from a mixture Mof L- and D-glufosinate P-alkyl ester hydantoins can be performed. The L-glufosinate P-alkyl ester obtained in the methods according to the first or second aspect of the invention may be saponified to give L-glufosinate.
