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

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

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

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.

Cholinergic modulation on the regulation of tyrosine hydroxylase was studied in guinea pig atria depolarized with high potassium concentration. In these conditions there was an increment in tyrosine hydroxylase activity as well as in the release of radioactivity from atria
