Study on the interaction between hemoglobin Izu (Macaca) and organic phosphates by spin labeling.
ESR spectra of the carbonmonoxy, oxy, and deoxy derivatives of hemoglobin Izu [Hb Izu (Macaca): beta 83 (EF 7) Gly leads to Cys] labeled at cysteine beta 83 with maleimide spin label have been observed in the presence and absence of 2,3-diphosphoglycerate and inositol hexaphosphate. The tau c 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.
