摘要：Process for the preparation of L -amino acids from their racemic N-acetyl-D,Lderivatives by enzymatic resolution by means of isolated, recombinant enzymesA processfor the preparation of proteinogenic or nonproteinogenic L-amino acids, in particular L-phosphinothricin, from their racemic N-acetyl-D,L derivatives comprisesa) selectivelydeacetylating N-acetyl-L derivatives of the corresponding L-amino acids by an enzymaticresolution by means of isolated, recombinant enzymes, while N-acetyl-D derivatives ofthe corresponding D-amino acids are not deacetylated and(b) separating the

deacetylated L-amino acids obtained preparatively from the nondeacetylated N-acetyl-Dderivatives and/or the incompletely deacetylated N-acetyl-L derivatives.
