We have demonstrated for the first time that d-glutamine (d-Gln) and d-glutamic acid (d-Glu) can be efficiently obtained in high ee (97% and 90%, respectively) by enzymatic kinetic resolution of d, l-Gln and d, l-Glu. This was achieved by enantioselective conversion of the l- enantiomers to their N-phenylacetyl derivatives in aqueous solution, using a mutant of penicillin-G acylase (PGA) from E. coli and phenylacetic acid methylester as the acyl ...
