Oxidation state of binuclear iron site in azidosemimethemerythrin.
Electron paramagnetic resonance spectra of azidosemimethemerythrin (from Phascolopsis gouldii) have been integrated to find the total number of spins per monomer unit. The value observed, 1.0 +/- 0.1 spins per Fe2 pair, confirms the assignment of a hybrid oxidation state, FeIIFeIII, to each site.
