Tyrosine 3-monooxygenase

UniProtKB accession:  P04177

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the conversion of L-tyrosine to L-dihydroxyphenylalanine (L-Dopa), the rate-limiting step in the biosynthesis of cathecolamines, dopamine, noradrenaline, and adrenaline. Uses tetrahydrobiopterin and molecular oxygen to convert tyrosine to L-Dopa (By similarity). In addition to tyrosine, is able to catalyze the hydroxylation of phenylalanine and tryptophan but with lower specificity (PubMed:10933781, PubMed:11922614). Positively regulates the regression of retinal hyaloid vessels during postnatal development (By similarity).
