PRODUCTION OF AMINO ACIDS AND ENZYMES USED THEREFOR

摘要

A process for producing .alpha.-amino acid from starting material comprising .alpha.-amino amide enantiomers (A) and (B) is such that enantiomer (A) is converted preferentially over enantiomer (B) so that a time independent excess of at least 90 %, preferably at least 98 % is given. The reaction is catalysed by an amidase which may in particular be produced by specific Rhodococcus species.
