Pertussis Toxin, Salt-Free, Bordetella pertussis
Islet-activating Protein
A protein endotoxin that catalyzes ADP-ribosylation of guanine nucleotide-binding regulatory proteins. The holotoxin has five dissimilar subunits S-1, S-2, S-3, S-4, and S-5, in a molar ratio of 1:1:1:2:1, S-1 (A protomer) is responsible for the enzymatic activity of the toxin, and S-2, S-3, S-4, and S-5 form the B oligomer which is responsible for the toxins binding to the cell surface. NOTE: This product is not activated, hence for use in cell-free systems, activation is required.
