A new microbial inhibitor for rat-liver phenylalanine hydroxylase (L-phenylalanine, tetrahydropteridine: oxygen oxidoreductase (4-hydroxylating), EC 1.14.16.1) was isolated from a culture medium of Fomes tasmanicus, and its structure was determined as 3,4-dihydroxystyrene. This compound inhibited the enzyme by 50% at a

The pH optimum of rat liver phenylalanine hydroxylase is dependent on the structure of the cofactor employed and on the state of activation of the enzyme. The tetrahydrobiopterin-dependent activity of native phenylalanine hydroxylase has a pH optimum of about 8.5.

A monoclonal anti-idiotype antibody, NS7, previously shown to mimic the binding of the pterin cofactor of phenylalanine hydroxylase (phenylalanine 4-monooxygenase, EC 1.14.16.1) has been used to localize the cofactor binding site within the phenylalanine hydroxylase catalytic domain to a 27-amino-acid

Phenylalanine hydroxylase (PAH) is a pterin-dependent non-heme metalloenzyme that catalyzes the oxidation of phenylalanine to tyrosine, which is the rate-limiting step in the catabolism of Phe. Chromobacterium violaceum phenylalanine hydroxylase (cPAH) has been prepared and its steady-state mechanism has been

A simple and rapid method for isolating tryptophan 5-monooxygenase [L-tryptophan, tetrahydropteridine:oxygen oxidoreductase (5-hydroxylating), EC 1.14.16.4] was reported. The method involves adsorption on calcium phosphate gel and affinity chromatography on agarose coupled with dimethyltetrahydropteridine. Tryptophan 5-monooxygenase was purified 1,100-fold from a
