Identification of the Allosteric Site for Phenylalanine in Rat Phenylalanine Hydroxylase* [PDF]

open access: yesJournal of Biological Chemistry, 2016
Liver phenylalanine hydroxylase (PheH) is an allosteric enzyme that requires activation by phenylalanine for full activity. The location of the allosteric site for phenylalanine has not been established. NMR spectroscopy of the isolated regulatory domain (RDPheH(25-117) is the regulatory domain of PheH lacking residues 1-24) of the rat enzyme in the ...
