| cooperativity | Phenomenon displayed by enzymes or receptors that have multiple binding sites. Binding of one ligand alters the affinity of the other site. Both positive and negative cooperativity are known, positive cooperativity gives rise to a sigmoidal binding curve. Cooperativity is often invoked to account for nonlinearity of binding data, although it is by no means the only possible cause. (18 Nov 1997) |

| cooperativity model | A model used to explain the property of cooperativity observed in certain enzymes; e.g., allosterism or hysteresis. (05 Mar 2000) |
| positive cooperativity | Cooperativity in which successive ligand molecules appear to bind with increasing affinity. (05 Mar 2000) |
|---|---|
| negative cooperativity | Cooperativity in which successive ligand molecules appear to bind with decreasing affinity. (05 Mar 2000) |
