-
the inactive form of GOase can be reactivated by further reduction to form the active copper(I) complex or reformation of the radical by single-electron oxidation. In practice, only reoxidation, and not further reduction, of the inactive state is performed to ensure a fully active enzyme, typically using mild chemical oxidants such as potassium ferricyanide
-
in the active form of GAO, the copper atom is at oxidation state +2 and the tyrosine is in a radical form. Reduction of the tyrosine radical generates the inactive form of GAO, which can be rescued by treating the inactive form with mild oxidants, such as, hexacyanoferrate (III), iridium (IV) chloride, molybdic cyanide, sodium periodate, potassium dichromate, or copper sulfate. Peroxidases can also enhance the action of GAO by oxidizing the inactive form to the active radical form
