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