发明名称 A METHOD FOR THE PRODUCTION OF L-AMINO ACIDS FROM THEIR RACEMIC N-ACETYL-D,L-DERIVATIVES USING ENZYMATIC RACEMATE CLEAVAGE BY MEANS OF ISOLATED RECOMBINANT ENZYMES
摘要 The invention rotates to a method for the production of proteinogenic or non-proteinogenic L-amino acids, especially L-phosphinothricin, from their racemic N-acetyl-D,L-derivatives. The method is characterized in that: N-acetyl-L-derivatives of the corresponding L-amino acids are selectively deacetylated by enzymatic racemate cleavage by means of isolated recombinant enzymes while the N-acetyl-D-derivatives of me corresponding D-amino acids are not deacetylated and the deacetylated L-amino acids are preparatively separated from the non-deacetylated N-acetyl-D-derivatives and/or the incompletely deacetylated N-acetyt-L-derivatives.
