Allosteric Effects The specificity of a ligand binding site on a protein is based on the presence of hydrating water molecules the amino acid residues lining the binding site the absence of competing ligands the opposite chirality of the binding ligand the presence of hydrating water molecules the amino acid residues lining the binding site the absence of competing ligands the opposite chirality of the binding ligand ANSWER DOWNLOAD EXAMIANS APP
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
