==Mechanism of pertussis toxin==
Pertussis toxin (PTX) acts on target cells through its A protomer which contains the '''enzymatically active S1 subunit'''. <br />
Pertussis toxin acts on target cells through its A protomer which contains the '''enzymatically active S1 subunit'''. <br />
This subunit catalyzes '''ADP-ribosylation''' of the ''α-subunit of trimeric G proteins'', which disturbs functions of the target cells and therefore lead to various biological effects.
