  • Q:

    Clostridium botulinum is a common soil bacterium. Unlike some other obligate anaerobes, C. botulinum is able to survive in the presence of oxygen with the help of certain metabolic antioxidants. Which of the following enzymes would you expect to find in C. botulinum that you would not find in non-aerotolerant anaerobes?

     

    A

    pyruvate dehydrogenase (pyruvate → acetyl CoA)

    B

    carbonic anhydrase (CO2 + H2O ↔ H2CO3)

    C

    superoxide dismutase (O2- → H2O2)

    D

    monoamine oxidase (RCH2NH2 ↔ RCHO)
