<P> The single - stranded nature of protein molecules , together with their composition of 20 or more different amino acid building blocks , allows them to fold in to a vast number of different three - dimensional shapes , while providing binding pockets through which they can specifically interact with all manner of molecules . In addition , the chemical diversity of the different amino acids , together with different chemical environments afforded by local 3D structure , enables many proteins to act as Enzymes , catalyzing a wide range of specific biochemical transformations within cells . In addition , proteins have evolved the ability to bind a wide range of cofactors and Coenzymes , smaller molecules that can endow the protein with specific activities beyond those associated with the polypeptide chain alone . </P>
