A binding site is a specific region on a molecule, typically a protein or nucleic acid, where another molecule, such as a ligand (which can be a drug, hormone, or another protein), attaches or interacts. This interaction often involves non-covalent forces, such as hydrogen bonds, ionic bonds, hydrophobic interactions, and Van der Waals forces. Binding sites are crucial for biological processes, as they play a key role in enzyme activity, signal transduction, and molecular recognition.
