Experiments on the Bacterial Serine Protease Subtilisin Show That Even

question 9

Multiple Choice

Experiments on the bacterial serine protease subtilisin show that even when all three residues of the catalytic triad are mutated, the catalytic rate of the enzyme is still 3000 times the uncatalyzed reaction rate. Which mode of catalysis is likely responsible for this remaining catalytic activity?

• A) acid-base catalysis
• B) covalent catalysis
• C) transition-state stabilization
• D) hydrophobic effects
