Allosteric Effects The conformational changes from the T to the R state is initiated by movement of the F-helix, which contains the proximal His binding of oxygen to the heme movement of the proximal histidine towards the heme reorganization of protein-protein contacts between the individual subunits movement of the F-helix, which contains the proximal His binding of oxygen to the heme movement of the proximal histidine towards the heme reorganization of protein-protein contacts between the individual subunits ANSWER DOWNLOAD EXAMIANS APP
