PKU can result from defects in phenylalanine hydroxylase (PAH), an enzyme that converts phenylalanine into amino acid tyrosine. It has been hypothesized that phenylalanine is both the substrate and an allosteric regulatory molecule for PAH. If this hypothesis is true, complete two models to show how PAH would appear if phenylalanine concentration were low (inactive enzyme) or high (active enzyme).
