Protein Denaturation:

1) If changing the pH of an enzyme solution greatly reduces the activity of that enzyme without precipitation, how could you tell in the lab if it were the result of denaturation or just going to a pH that is just not a good one for the enzyme? And how would a change in pH impact or even stop enzyme function without denaturation? (Consider the enzymes that are active in your stomach, such as pepsin-discussed in Wikipedia.)

2) For changes that precipitate a protein, are some more likely than others to be denaturation?

Denaturation can occur if a protein is heated or undergoes changes in pH. Denaturation disrupts the secondary, tertiary, and quaternary structure of a protein. Would you expect the Biuret test to work on a protein that had been denatured? Why or why not?

Topic: Protein Denaturation 1) What are the various levels of organization that any protein structure may have that gives it its 3D shape? Which of these changes during denaturation? 2) For each change made to a protein solution, how might it affect the interactions that are involved in a protein's shape? 3) What is the difference between precipitation of a protein and its denaturation? How might you tell the difference?

An enzyme has a broad pH optimum having high rates of activity between pH 4 and 12. X-ray diffraction studies show that the enzyme has an active site with glutamate and arginine residues in close proximity to the substrate. Explain how these two residues might be able to promote concerted acid-base catalysis (which residue is acting as the acid, which is acting as the base). Finally, explain why enzyme activity drops off sharply below pH 4 and above pH 12.
