Abstract

Phenylalanine hydroxylase is a liver enzyme protein that belongs to the class of hydrolases, which means that they break chemical bonds when exposed to water. The mentioned enzyme catalyses the reaction of conversion of one amino acid (L-phenylalanine) into another (L-tyrosine). More precisely, this reaction consists in the addition of the – OH group to the carbon at the 4-position of the tyrosine.

Keywords: phenylalanine hydroxylase, exogenous, enzyme
