[[http://www.uniprot.org/uniprot/TOX4_BORPE TOX4_BORPE]] PTX oligomer B binds to receptors on the eukaryotic cell surface and facilitates the translocation of the toxic subunit across the cell membrane. [[http://www.uniprot.org/uniprot/TOX1_BORPE TOX1_BORPE]] S1 is an NAD-dependent ADP-ribosyltransferase, which plays a crucial role in the pathogenesis of B.pertussis causing disruption of normal host cellular regulation. It catalyzes the ADP-ribosylation of a cysteine in the alpha subunit of host heterotrimeric G proteins. In the absence of G proteins it also catalyzes the cleavage of NAD(+) into ADP-ribose and nicotinamide. It irreversibly uncouples the G-alpha GTP-binding proteins from their membrane receptors. [[http://www.uniprot.org/uniprot/TOX3_BORPE TOX3_BORPE]] PTX oligomer B binds to receptors on the eukaryotic cell surface and facilitates the translocation of the toxic subunit across the cell membrane. [[http://www.uniprot.org/uniprot/TOX2_BORPE TOX2_BORPE]] PTX oligomer B binds to receptors on the eukaryotic cell surface and facilitates the translocation of the toxic subunit across the cell membrane. [[http://www.uniprot.org/uniprot/TOX5_BORPE TOX5_BORPE]] PTX oligomer B binds to receptors on the eukaryotic cell surface and facilitates the translocation of the toxic subunit across the cell membrane.
