pertussis toxin
<protein> Protein complex (ca 117 kD). An A B toxin, the active subunit is a single polypeptide 28 kD), the binding subunit a pentamer (two heterodimers, 23 + 11.7 kD, 11.7 + 22 kD and a monomer (9.3 kD) that binds the heterodimers). The active subunit ADP ribosylates the _ subunit of the inhibitory GTP-binding protein (Gi). Crucial to the pathogenicity of Bordetella pertussis, the causative agent of whooping cough.
