Protein Function
Allosteric Proteins: Positive and Negative Effects
Description
Allosteric proteins have more than one ligand binding site. A ligand is a molecule that binds to a protein. When a ligand binds at one site, it can affect binding at the other sites. These sites are called coupled or linked because they influence one another.
In enzymes, the site that binds the s...

Transcript
Most proteins have multiple locations where ligands can associate, in addition to the site responsible for protein function. Binding of a molecule to any of these sites often results in conformational changes, altering the shape of the protein.
When this change affects the binding of another ligand, the two sites are described as coupled...
