 The action of cholera toxin
Fig 3. The action of cholera toxin. The complete toxin is shown binding to the
GMI-ganglioside receptor on the cell membrane via the binding (B) subunits. The active
portion (A1) of the A subunit catalyzes the adenosine diphosphate (ADP)–ribosylation of
the Gs (stimulatory) regulatory protein, “locking” it in the active state. Because the G
protein acts to return adenylate cyclase from its active to inactive form, the net effect is
persistent activation of adenylate cyclase. The increased adenylate cyclase activity results
in accumulation of cyclic adenosine 3’ 5’-monophosphate (cAMP) along the cell
membrane. The cAMP causes the active secretion of sodium (Na), chloride (Cl−),
potassium (K+), bicarbonate (HCO3 −), and water out of the cell into the intestinal lumen.
