Webb27 sep. 2000 · When a protein binds a ligand, hydrogen ions may be liberated or consumed. When this occurs, the apparent equilibrium constant K‘ for the dissociation of the ligand will be a function of pH. Thus, the study of the dependence of K‘ on pH can provide information on the acid dissociation constants of acid groups in the binding site … WebbProtein A is a 42 kDa surface protein originally found in the cell wall of the bacteria Staphylococcus aureus. It is encoded by the spa gene and its regulation is controlled by DNA topology, cellular osmolarity, and a two-component system called ArlS-ArlR. It has found use in biochemical research because of its ability to bind immunoglobulins.

Binding usually occurs when a drug associates with a macromolecule in an aqueous environment but may occur when a drug is partitioned into body fat. Because fat is poorly perfused, equilibration time is long, especially if the drug is highly lipophilic.

WebbThe set of amino acid residues around a binding pocket determines its physicochemical characteristics and, together with its shape and location in a protein, defines its functionality. Residues outside the binding site can also have a long-range effect on the properties of the binding pocket. WebbDrugs are designed to primarily cause one effect, meaning they bind more strongly to one specific receptor site and predictably cause or block an action. ...
