Abstract

The phenylalanine aminomutase from Taxus catalyzes the vicinal exchange of the amino group and the pro-3 S hydrogen of (2 S)-α-phenylalanine to make (3 R)-β-phenylalanine. While the migration of the amino group from C2 of the substrate to C3 of the product is already known to proceed intramolecularly with retention of configuration, the stereochemistry of the hydrogen transfer remained unknown, until now. The chemical ...
