Chemistry informtion about Cholera Toxin (9012-63-9) is:
Synonyms: Cholera Toxin ; Cholera Enterotoxin ; Cholera Toxin, Vibrio Cholerae, Type Inaba 569b ; Vibrio Cholerae Toxin ; Choleraentero-Exotoxin ; Choleraexotoxin ; Choleragen ; Exo-Enterotoxin
Storage temp.: 0-6°C

The gene encoding the cholera toxin is introduced into V. cholerae by horizontal gene transfer. Virulent strains of V. cholerae carry a variant of lysogenic bacteriophage called CTXf or CTXφ.

 Cholera Toxin (9012-63-9) has been used as a neuronal tracer.Also,it can be used to identify rafts.

A poison by intravenous route. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating vapors.
RIDADR: 3172
HazardClass: 6.1
PackingGroup: I

 Cholera Toxin (9012-63-9) is an oligomeric complex made up of six protein subunits: a single copy of the A subunit (part A), and five copies of the B subunit (part B). The two parts are connected by a disulfide bond. The three-dimensional structure of the toxin was determined using X-ray crystallography by Zhang et al. in 1995. The five B subunits—each weighing 12 kDa, and all coloured blue in the accompanying figure—form a five-membered ring. The A subunit has two important segments. The A1 portion of the chain (CTA1, red) is a globular enzyme payload that ADP-ribosylates G proteins, while the A2 chain (CTA2, orange) forms an extended alpha helix which seats snugly in the central pore of the B subunit ring.This structure is similar in shape, mechanism, and sequence to the heat-labile enterotoxin secreted by some strains of the Escherichia coli bacterium.
