Tyrosine 3-monooxygenase.
based on mapping to UniProt P07101
L-tyrosine + tetrahydrobiopterin + O(2) = L-dopa + 4a-hydroxytetrahydrobiopterin.
-!- Activated by phosphorylation, catalyzed by EC 2.7.11.27. -!- The 4a-hydroxytetrahydrobiopterin formed can dehydrate to 6,7- dihydrobiopterin, both spontaneously and by the action of EC 4.2.1.96. -!- The 6,7-dihydrobiopterin can be enzymically reduced back to tetrahydrobiopterin, by EC 1.5.1.34, or slowly rearranges into the more stable compound 7,8-dihydrobiopterin.
