1 The EPR spectrum of the binuclear Co(II) derivative contains a resonance at g approximately 13, which is characteristic of integer spin systems and indicates coupled metal ions; the excess Co(II) bound to crude products exhibits an EPR signal at g approximately 4.

2 The intensity of the optical absorption in the visible region due to Co(II) increases with increasing stoichiometry of specifically bound metal [up to 2 Co(II) per protein monomer], but the intensity of the Co(II) EPR signal increases only during the formation of a mononuclear derivative.
