Allosteric Effects
Bisphosphoglycerate (BPG) cannot bind to the oxygenated R state of hemoglobin because

it is displaced from the heme by oxygen
BPG binds to the R state with the same affinity as the T state
it is displaced from the heme by movement of the proximal histidine
its binding pocket becomes too small to accommodate BPG
