WebMar 24, 2024 · A new cofactor the facilitates electron flow in the conversion of Phe to Try in the first step, catalyzed by the enzyme tyrosine hydrolase, is required. That cofactor is tetrahydrobiopterin (BH 4 ). The reaction involves the hydroxylation of BH 4 and then its transfer to phenylalanine. L-Phenylalanine is biologically converted into L-tyrosine, another one of the DNA-encoded amino acids. L-tyrosine in turn is converted into L-DOPA, which is further converted into dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline). The latter three are known as the catecholamines. Phenylalanine uses the same active transport channel as tryptophan to cross the blood–brain bar…
