A method for producing an optically active amino acid, which comprises adding ammonia to an acrylic acid derivative by action of a plant enzyme and obtaining the corresponding optically active amino acid. The method for producing an L-amino acid, which comprises, in the presence of ammonia, allowing phenylalanine ammonia-lyase derived from a plant to act on an acrylic acid derivative, which may have an aromatic ring group that may have various substituents and comprise a hetero atom.

La présente invention concerne un procédé de production d'un amino-acide optiquement actif. Ledit procédé consiste à ajouter de l'ammoniac à un dérivé d'acide acrylique par action d'une enzyme végétale et à obtenir l'amino-acide optiquement actif correspondant. Ledit procédé de production d'un L-amino acide, qui consiste, en présence d'ammoniac, à permettre à la phénylalanine ammoniac-lyase dérivée d'un végétal d'agir sur un dérivé d'acide acrylique, qui peut posséder un groupe à cycle aromatique qui peut présenter divers substituants et comprendre un hétéroatome.
