<P> Protein tertiary structure is the three dimensional shape of a protein . The tertiary structure will have a single polypeptide chain `` backbone '' with one or more protein secondary structures , the protein domains . Amino acid side chains may interact and bond in a number of ways . The interactions and bonds of side chains within a particular protein determine its tertiary structure . The protein tertiary structure is defined by its atomic coordinates . These coordinates may refer either to a protein domain or to the entire tertiary structure . A number of tertiary structures may fold into a quaternary structure . </P>
