Pertussis toxin is an ADP ribosylating A-B toxin with two components:
  1. A (Active) component ADP-ribosylates Gi by removing the ADP-ribosyl group from NAD and covalently attaching it to Gi which causes Gi inactivation and subsequently increased cAMP, increased secretion of Na+, Cl-, H2O from cells, edema, and neutrophil dysfunction.
  2. B (Binding) component facilitates endocytosis.


^ is this more or less accurate?
