ESR spectra of the carbonmonoxy, oxy, and deoxy derivatives of hemoglobin Izu [Hb Izu (Macaca): ß 83 (EF 7) Gly
Cys] labeled at cysteine ß 83 with maleimide spin label have been observed in the presence and absence of 2,3-diphosphoglycerate and inositol hexaphosphate. The rc values obtained from the spectra indicated that inositol hexaphosphate binds to all the derivatives of Hb Izu, but 2,3-diphosphoglycerate only to the deoxy derivatives.
