WebATCase is composed of two catalytic trimers three regulatory dimers Cooperativity is the influence that the binding of one ligand to one protomer has on the binding of another ligand to a second protomer (or oligomeric protein) Ligand may be substrate, inhibitor, or activator. Binding of an allosteric activator/inhibitor WebWhy might it have been surprising to find that CTP inhibits ATCase? The substrates for ATCase are carbamoyl phosphate and aspartate. Neither of these molecules resemble CTP. Thus it was clear that the CTP must not bind to the active site but to a distinct regulatory site.
