Anaerobic Respiration - Exercise #2
E. coli can use many different combinations of enzyme complexes to oxidize electron donors and reduce electron acceptors. When formate is oxidized, DMSO reductase and nitrate reductase A can be a partner to formate dehydrogenase in an electron transport chain.
- Compare and contrast DMSO reductase and nitrate reductase A in the electron transport chain with formate dehydrogenase; what is similar what is different.
- You are interested in how the expression of both DMSO and nitrate reductase operons is regulated. Based on the information that you find in EcoCyc, compare and contrast the regulation of expression of both operons.
