an aromatic amino acid + glyoxylic acid an aromatic oxo acid + glycine

Thus, the two substrates of this enzyme are aromatic amino acid and glyoxylic acid. Its products are the corresponding α-keto acid and glycine.

For example, the enzyme characterised from liver interconverts phenylalanine and phenylpyruvic acid:[1]

This enzyme is a transferase, specifically a transaminase, which transfer nitrogenous groups. The systematic name of this enzyme class is aromatic-amino-acid:glyoxylate aminotransferase.[2]
