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).
In the Lock and Key Model, first presented by Emil Fisher, the lock represents an enzyme and the key represents a substrate.ock and Key Analogy. The active site is the binding site for catalytic and inhibition reaction of the enzyme and the substrate; structure of active site and its chemical characteristic are of specificity for binding of substrate and enzyme.
