Simple Change in Primary Structure Even a slight change in primary structure
can affect a protein's conformation and ability to function . For instance , the
one polypeptide chain have a quaternary level of structure . Protein shape is
ultimately determined by its primary structure , but the structure and function of a
protein are sensitive to physical and chemical conditions . Activity Protein
