catalyzed by aminotransferases producing 4-hydroxyphenylpyruvic acid and amino acids such asl-glutamic acid, or catalyzed by amino acid oxidase producing the phenylpyruvic acid, ammonia, and NADH. The second step isdecarboxylationof 4-hydroxyphenylpyruvic acid to produce 4-hydroxyphenyacetic acid[99]...
