    REGULATION
    Other complexly regulated by its substrate L-Phenylalanine and its natural cofactor 6R-L-erythro-5,6,7,8-tetrahydrobiopterin (BH(4))
    regulated by both arginine AA and exon 7 which is of great significance with regards to the structure and function of the PAH enzyme
    regulated by three main mechanisms, substrate (L-Phe) activation, pterin cofactor inhibition and phosphorylation of a single serine (Ser16) residue
