Binding of inositol hexakisphosphate to the oxygenated derivative of dromedary (Camelus dromedarius) and human hemoglobin: 31P-NMR study.
Binding of inositol hexakisphosphate (IHP) to the oxygenated derivative of dromedary (Camelus dromedarius) and human hemoglobin (Hb) was investigated by 31P-NMR. The results obtained show that dromedary Hb binds, with different affinity, two IHP molecules per tetramer at distinct sites, while human Hb binds only one IHP molecule per tetramer.
