Abstrakt: Vanadyl ions may be used for reactivation of apodopamine beta-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.
