Question: Compare and contrast the enzymes catalase superoxide dismutase and superoxide
Compare and contrast the enzymes catalase, superoxide dismutase, and superoxide reductase as regards their substrates and products.
Answer to relevant QuestionsContrast the terms thermal death time and decimal reduction time. How would the presence of bacterial endospores affect either value? How do cells of Escherichia coli that carry a mutation in mreB ( the gene encoding the protein MreB) look different microscopically from wild- type ( unmutated) cells? What is the reason for this? Escherichia coli but not Pyrolobus fumarii will grow at 40° C, while P. fumarii but not E. coli will grow at 110° C. What is happening (or not happening) to prevent growth of each organism at the nonpermissive temperature? Explain how chromosomal islands might move between different bacterial hosts. Describe how one might determine which proteins in Escherichia coli are repressed when a culture is shifted from a minimal medium (containing only a single carbon source) to a rich medium containing many amino acids, bases, ...
