  • Publication number: 20100285540
    Abstract: A process for producing (R)-?-arylalanines is described. The process converts (S)-?-arylalanine to (R)-?-arylalanine using phenylalanine aminomutase and amino acid racemase. The (R)-?-arylalanine product can be used to form pharmaceutically useful drugs. Also disclosed are DNA sequences encloding phenylalanine aminomutase and amino acid racemase enzymes, sequences for PCR primers of the DNA sequences, and sequences for expressed aminomutase and amino acid racemase enzymes.
