Description

General description

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.

A protein endotoxin that catalyzes ADP-ribosylation of guanine nucleotide-binding regulatory proteins. Used in the study of adenylate cyclase regulation and the role of G_i 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 the other subunits (2-5) form the B oligomer which is responsible for the toxin′s binding to the cell surface. Note: This product is not activated. If used with an intact cell system, the cells will activate the toxin. If used in a cell-free system, product may be activated by the methods of either Kaslow and Burns or Moss at al.(see references).

Pertussis Toxin, Bordetella pertussis, Glycerol Solution, CAS 70323-44-3, is a protein endotoxin that catalyzes ADP-ribosylation of guanine nucleotide-binding regulatory proteins.
