Phenylalanine synthesis pathway
WebPhenylalanine cannot be converted into tyrosine and, as shown in figure 7-25, it forms phenyl-pyruvic, phenyl-lactic and phenyl acetic acids (the latter is eliminated in urine in a … Web( PAH) ( EC 1.14.16.1) is an enzyme that catalyzes the hydroxylation of the aromatic side-chain of phenylalanine to generate tyrosine. PAH is one of three members of the biopterin -dependent aromatic amino acid hydroxylases, a class of monooxygenase that uses tetrahydrobiopterin (BH 4, a pteridine cofactor) and a non-heme iron for catalysis.
