polar, non-polar, and charged side chains. 3 points) ucture of folded globular proteins, in particular where you would oould he loeted ins de Polar side chans uoald loe located outside DUA 2. Proteins often have regions that can fold and function as an independent entity from the whole protein. These regions are called: (3 points) Protein S will fold into its native conformation only when protein Q is also present in the solution. However, protein Q can fold into its native conformation without protein S. Protein Q, therefore, may function as for 3. afor protein S. 3 points) Describe the Anfinsen ribonuclease experiment and what conclusions were drawn about protein folding. (3 points) 4. 5. The folding of the structure of a protein through conformation changes following removal of the unfolding reagent is process called: (3 points) 6. What is (are) the major interaction(s) that drive protein folding? Explain your answers. (3 points) Which amino acid(s) can stabilize protein tertiary structures by forming covalent cross-links between polypeptide chains? (3 points) 7.

Explanation / Answer

3) Protein S will fold into the native conformation only when Q protein is also present in the solution. However protein Q will fold into its native conformation without protein S. Protein Q may therefore function as chaperon for protein S.

Chaperons are the proteins that help to fold or unfold other macromolecules in the cells.
