On … WebCooperative binding occurs if the number of binding sites of a macromolecule that are occupied by a specific type of ligand is a nonlinear function of this ligand's concentration. This can be due, for instance, to an affinity for the ligand that depends on the amount of ligand bound. Cooperativity can be positive (supralinear) or negative ...

WebHormone binding exposes regions of the receptor that have DNA-binding activity, meaning they can attach to specific sequences of DNA. These sequences are found next to certain genes in the DNA of the cell, and … WebFeb 13, 2013 · 13A. Allosteric Effects and Cooperativity: Allosteric effects are the change in the conformation of a protein due to binding of a ligand. Cooperative effects occur when the binding properties of the protein towards ligands change as a consequence of another ligand binding to the protein. There need not be a direct connection between the two ... Webbinding: i) Non-cooperative. The binding constant remains the same for both binding events. ii) Positive cooperativity if KD2 < KD1 (or K2 > K1) i.e. the second binding is higher in affinity. iii) Negative cooperativity if KD2 > KD1 (or K2 < K1) i.e. the second binding is lower in affinity.
