Recombinant Bordetella pertussis Pertussis toxin subunit 1 (ptxA)
| Product Name | Recombinant Bordetella pertussis Pertussis toxin subunit 1 (ptxA) |
|---|---|
| Description | 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 mbrane receptors. |
