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).
Structural Biochemistry/Enzyme/Active Site 1 Structural Biochemistry/Enzyme/Active Site Overview An active site is the part of an enzyme that directly binds to a substrate and carries a reaction.he binding of thesubstrate to the enzyme causes changes in the chemical bonds of the substrate and causes the reactions that lead tothe formation of products. The products are released from the enzyme surface to regenerate the enzyme for anotherreaction cycle.
