Interaction Information:
Comment | Phe is an essential amino acid obtained exclusively by the diet or by proteolysis. Phenylalanine is hydroxylated to tyrosine by PAH, found in liver and kidney. Alternatively phenylalanine is converted to phenylpyruvic acid (PPA), which is catalyzed by the enzyme phenylalanine (histidine) transaminase (EC 2.6.1.58), found mainly in liver. This reaction is activated by the substrate phenylalanine and might therefore become more relevant if phenylalanine levels are high. The third pathway is the decarboxylation of phenylalanine to phenylethylamine by phenylalanine decarboxylase (EC 4.1.1.53). |
