Abstract

The structure of a phenylalanine aminomutase (Tc PAM) from Taxus canadensis has been determined at 2.4 Å resolution. The active site of the Tc PAM contains the signature 4- methylidene-1 H-imidazol-5 (4 H)-one prosthesis, observed in all catalysts of the class I lyase-like family. This catalyst isomerizes (S)-α-phenylalanine to the (R)-β-isomer by exchange of the NH2/H pair. The stereochemistry of the Tc PAM reaction product is ...
