The substrate specificity of a Taxus-derived phenylalanine aminomutase (PAM) was investigated, and the enzyme was found to catalyze the conversion of variously substituted vinyl- and aryl-S-alpha-alanines to corresponding beta-amino acids. This study shows the broad substrate specificity of PAM and thus demonstrates a potential, practical biosynthetic route toward unnatural beta-amino acid subunits of Taxol analogues and beta-peptides.
