  Stereochemistry and Mechanism of a Microbial Phenylalanine Aminomutase

  摘要：

  The stereochemistry of a phenylalanine aminomutase (PAM) on the andrimid biosynthetic pathway in Pantoea agglomerans (Pa) is reported. PaPAM is a member of the 4-methylidene-1H-imidazol-5(4H)-one (MIO)-dependent family of catalysts and isomerizes (2S)-alpha-phenylalanine to (3S)-beta-phenylalanine, which is the enantiomer of the product made by the mechanistically similar aminomutase TcPAM from Taxus plants. The NH2 and pro-(3S) hydrogen groups at C-alpha and C-beta, respectively, of the substrate are removed and interchanged completely intramolecularly with inversion of configuration at the migration centers to form P-phenylalanine. This is a contrast to the retention of configuration mechanism followed by TcPAM.
