Invasive adenylate cyclase toxin of Bordetella pertussis.

Abstract

Bordetella pertussis produces an adenylate cyclase which is a toxin. The enzyme penetrates eukaryotic cells and, upon activation by host calmodulin, generates high levels of intracellular cAMP; as a result bactericidal functions of immune effector cells are considerably impaired. The toxin is composed of a single polypeptide that possesses both the catalytic and the toxic functions. It penetrates the host cell directly from the plasma membrane and is concomitantly inactivated by a proteolytic degradation.
