WebDegradation of phenylalanine Degradation of phenylalanine and Tyrosine are unique. A series of reactions occur that use molecular oxygen to break the aromatic ring. In the initial reaction, phenylalanine is hydroxylated by phenylalanine hydroxylase, a monooxygenase that utilizes oxygen and tetrahydrobiopterin a pteridine co-factor. WebIntroduction. Phenylketonuria (PKU; MIM# 261600) is a metabolic disease inherited in an autosomal recessive fashion. PKU is caused by mutations in the human phenylalanine hydroxylase gene (hPAH) which affect the structure and/or function of the phenylalanine hydroxylase enzyme (EC 1.14.16.1) thus decreasing the catabolism of l-phenylalanine …
