Phenylalanine Hydroxylase(<scene name='Sandbox_Reserved_480/Phenylalanine_hydroxylase/1'>PAH</scene>)is a type of enzyme involved in the catalization of phenylalanine into tyrosine.  
Phenylalanine Hydroxylase(<scene name='Sandbox_Reserved_480/Phenylalanine_hydroxylase/1'>PAH</scene>)is a type of enzyme involved in the catalization of phenylalanine into tyrosine. It belongs to the family of aromatic amino acid hydroxylases. Some other enzymes in this family include tyrosine hydroxylase and tryptophan hydroxylase. These enzymes require oxygen and forms of pterin to convert their amino acid substrates into products.

Phenylalanine hydroxylase is the rate limiting exzyme invovled in the metabolism of phenylalanine. With Fe (III), oxygen, and tetrahydrobiopterin, PheOH hydroxylates Phe into Tyr. Tyr goes on to make L-dopa and eventually dopamine.
