Abstract
A biocatalytic process to produce optically active phenylalanine analogs from arylacrylic acids is disclosed in which Rhodotorula graminis yeast containing phenylalanine ammonia-lyase introduces a molecule of ammonia stereoselectively onto the double bond of a 3-substituted acrylic acid. The substituent at the 3-position of the 3-substituted acrylic acid includes, for example, aromatic rings such as substituted phenyl groups, five member aromatic heterocyclics, and six member aromatic heterocyclics.
