WebCooperativity is the interaction process by which binding of a ligand to one site on a macromolecule (enzyme, receptor, etc.) influences binding at a second site, e.g. between the substrate binding sites of an allosteric enzyme. Cooperative enzymes typically display a sigmoid (S-shaped) plot of the reaction rate against substrate concentration .

WebJun 16, 2009 · In biochemistry the term cooperativity is almost always used in one particular context: binding-dissociation reactions at equilibrium. The classic example is the binding of oxygen to hemoglobin (Figure 1). But cooperativity is also important in cell-cell signaling, transcriptional regulation and more complex processes governing the behavior … WebThe proposed quinolone–DNA cooperative binding model may be used to interpret the large activity difference of ofloxacin enantiomers which have a chiral center located in the drug self-assembly domain. Ofloxacin, developed by Daiichi Seiyaku Company (Tokyo, Japan), has an antibacterial potency (Une et al., 1988) and supercoiling inhibition activity … my grown son is verbally abusive to me
