H. Q PDF files. A single protein molecule may contain one or more of these protein structure types. Protein Engineering Elucidates the Relationship between Structure, Function and Stability of a Metabolic Enzyme Reinhard Sterner, Thomas Schwab and Sandra SchleeTraditionally, there has been little if any cross-talk between the fields of protein biophysics, protein structure–function and molecular evolution. The highly complex nature of these relationships is a consequence of the interplay between physics and evolution that has been studied using a wide array of experimental and theoretical techniques. We addressed this issue by systematically looking at the relationship between protein function and structure. constituting 25% of the total protein mass in these animals. Denaturation occurs because the bonding interactions responsible for the secondary structure (hydrogen bonds to amides) and tertiary structure are disrupted.
