Phenylalanine hydroxylase (PAH)

Part Description

Phenylalanine hydroxylase (PAH) gene is the part responsible for providing instructions to make phenylalanine hydroxylase enzyme. this enzyme is responsible for hydroxylating phenylalanine and turning it to tyrosine in the presence of tetrahydrobiopterin (BH4). and as phenylalanine is present in almost all proteins and some artificial sweeteners this process of hydroxylation is really important to prevent its' accumulation.
also the product of tyrosine is used to make various homones and neurotransmitters.

Usage

Member of the 6 hydroxylase enzymes PAH process phenylalanine to be hydroxylated in order to produce tyrosine. PAH is a hydroxylase that needs biopterin that convert phenylalanine to tyrosine and in case of its absence or deficiency lead to a metabolic condition called Phenylketonuria that can occur in humans due to abnormalities in the gene that codes for it so we use this part to replace the deficient one and process phenylalanine into tyrosine
