Tyrosine hydroxylase
MAMMALIAN PROTEIN FOUND IN HOMO SAPIENS
Tyrosine 3-monooxygenase; Tyrosine hydroxylase inhibitor; Tyrosine-3-hydroxylase; EC 1.14.16.2; Tyrosine 3-hydroxylase; L-tyrosine,tetrahydrobiopterin:oxygen oxidoreductase (3-hydroxylating)
Tyrosine hydroxylase or tyrosine 3-monooxygenase is the enzyme responsible for catalyzing the conversion of the amino acid L-tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA). It does so using molecular oxygen (O2), as well as iron (Fe2+) and tetrahydrobiopterin as cofactors.
