The genome of the protozoan parasite Toxoplasma gondii was found to contain two genes encoding tyrosine hydroxylase; that produces L-DOPA. The encoded enzymes metabolize phenylalanine as well as tyrosine with substrate preference for tyrosine. Thus the enzymes catabolize phenylalanine to

European journal of pharmacology, 541(1-2), 33-37 (2006-06-06)
In the present study we have analyzed the effect of tetrahydrobiopterin (BH4) essential cofactor for tyrosine hydroxylase and nitric oxide synthase, on the 3,4-dihydroxyphenylalanine (L-DOPA) release from in vitro incubated striatal tissue. dl-6-methyl-5,6,7,8 tetrahydropterine (6-MPH4)-stimulated L-DOPA release in a concentration-dependent

Glial cell line-derived neurotrophic factor (GDNF) protects dopaminergic neurones against toxic and physical damage. In addition, GDNF promotes differentiation and structural integrity of dopaminergic neurones. Here we show that GDNF can support the function of primary dopaminergic neurones by triggering

A radiometric assay for tyrosine hydroxylase employing a coupled nonenzymatic decarboxylation of L-[14C]Dopa formed from L-[14C]tyrosine has been adapted for performance in a 96 microwell culture plate. The method uses an easily manufactured plate holder to compress blotting paper impregnated

There is controversy in the literature concerning the action of tetrahydropterines on the enzyme tyrosinase and on melanogenesis in general. In this study, we demonstrate that tetrahydropterines can inhibit melanogenesis in several ways: i) by non-enzymatic inhibition involving purely chemical
