Reaction: ATP + [tyrosine-3-monooxygenase] = ADP + phospho-[tyrosine-3-monooxygenase]
Other name(s): pheochromocytoma tyrosine hydroxylase-associated kinase; STK4; tyrosine 3-monooxygenase kinase (phosphorylating)
Systematic name: ATP:[tyrosine-3-monoxygenase] phosphotransferase
Comments: The enzyme has no activating compound but is specific for its substrate, with which it co-purifies. Requires Mg2+. Activates EC 18.104.22.168, tyrosine 3-monooxygenase, by phosphorylation.
