- The highly pathogenic anaerobic bacterium Clostridium perfringens is responsible for gas gangrene, a condition in which animal tissue structure is destroyed. This bacterium secretes an enzyme that efficiently catalyzes the hydrolysis of the peptide bond indicated in red: where X and Y are any of the 20 common amino acids. How does the secretion of this enzyme contribute to the invasiveness of this bacterium in human tissues? Why does thisenzyme not affect the bacterium itself?What is the mechanism of action of cisplantine as an anticancer agent?What is the underlying molecular mechanism of action for the antibiotic novobiocin?
- Gram-negative bacteria are surrounded by two membrane bilayers separated by a space termed the periplasm. The periplasm is a multipurpose compartment separate from the cytoplasm. The periplasm has a distinct oxidizing environment that allow certain key protein structural features to be formed. Can you identify an amino acid(s) that would be affected by this oxidizing environment? How would it be affected, and what structural features would be sensitive to this environment? Can you discuss the implications of this from a standpoint of recombinant protein expression?Some antibiotics target peptidoglycan synthesis. What is amolecular growth target of an antibiotic that inhibitspeptidoglycan synthesis?Consider the five E. coli merodiploid strains listed here.

What is the genotype of the bacteria in this E. coli colony?When bacteriophage P1 causes E. coli to lyse, the resulting materialis called a P1 lysate. What type of genetic material would befound in most of the P1 phages in the lysate? What kind of geneticmaterial is occasionally found within a P1 phage?In your laboratory, you have an F− strain of E. coli that is resistantto streptomycin and is unable to metabolize lactose, but it can metabolizeglucose. Therefore, this strain can grow on a medium thatcontains glucose and streptomycin, but it cannot grow on a mediumcontaining lactose. A researcher has sent you two E. colistrains in two separate tubes. One strain, let’s call it strain A, hasan F′ factor (an F prime factor) that carries the genes that are requiredfor lactose metabolism. On its chromosome, it also has thegenes that are required for glucose metabolism. However, it is sensitiveto streptomycin. This strain can grow on a medium containinglactose or glucose, but it cannot grow if streptomycin is addedto the medium. The second strain, let’s call it strain B, is an F−strain. On its chromosome, it has the genes that are required forlactose and glucose metabolism. Strain B is also sensitive to streptomycin.Unfortunately, when strains A and B were sent to you, thelabels had fallen…
