Some strains of bacteria or microorganisms have developed toxins that can modify the activity of the alpha subunit of G proteins which results in disease. For ex. cholera toxin, produced by Vibrio cholerae, causes ADP ribosylation of the stimulatory Gαs subunit of G proteins. This modification abolishes the GTPase of Gαs, and results in an αs subunit that is always in the “on” or active state. It results in continuous stimulation of adenylyl cyclase (AC). The main cells affected by this are the epithelial cell in gastrointestinal tract. Knowing this altered activity of AC, explain why patients affected by this toxin experience severe diarrhea and dehydration that may result in death.
Pay close attention to the information related to figure 3.14a and the structure of the PKA catalytic site in this figure.

ATP is both an inhibitor and substrate of adenyl cyclase. As a substrate, the enzyme converts ATP to cyclic AMP only when the energy sources of cells are low. cAMP mediates the synthesis of a kinase that adds a phosphate to glycogen synthase and phosphorylase.

What is the implication of the difference in Km value of the active and allosteric site in terms of the utilization of the stored sources of energy of cells? Explain.
