Protein Properties: Binding Sites [edit]. A binding site is a position on a protein that binds to an incoming molecule that is smaller in size comparatively, called ligand. In proteins, binding sites are small pockets on the tertiary structure where ligands bind to it using weak forces (non-covalent bonding).
â¢The active site of an enzyme contains the catalytic and binding sites. â¢The structure and chemical properties of the active site allow the recognition and binding of the substrate. â¢Protein functions such as molecular recognition and catalysis depend on complementarity.
