'''Phenylalanine Hydroxylase'''(PheOH), otherwise known as phenylalaine-4-monooxygenase, is an enzyme produced by the ''PAH'' gene found on the twelfth chromosome in the human genome, but it is also found in some bacteria. This enzyme functions as a catalyst in the conversion of the amino acids phenylalanine to tyrosine by adding a hydroxyl group (-OH) to the benzene ring of the amino acid. This is why this protein is therefore classified as a hydroxylase. In most organisms, this hydroxylation process is the first step in phenylalanine degradation. A faulty ''PAH'' gene can cause an increase in phenylalanine level in the plasma, resulting in the genetic disorder Phenylketonuria (PKU).<ref> College, Davidson.
