The reactivation of apodopamine β-monooxygenase by vanadyl ions

AbstractVanadyl ions may be used for reactivation of apodopamine β-monooxygenase. Maximal activity of the enzyme was achieved at a 350–400-fold molar excess of vanadyl ions, whereas for maximal reconstitution with copper, an 8–10-fold molar excess of copper was necessary. At higher concentrations of vanadyl as well as of copper, inhibition was observed
