| Hazard Information | Back Directory | [Uses]
The toxin is released from B. pertussis in an inactive form. When the pertussis toxin B oligomer binds to the cell membrane, the S1 subunit of its A protomer becomes activated, perhaps through the action of glutathione and ATP. A protocol for activating pertussis toxin in vitro is given by Kaslow, et al. | [General Description]
Product is not activated. If activation is required, see Kaslow, et al., for suggested conditions. | [Biochem/physiol Actions]
Pertussis toxin catalyzes the ADP-ribosylation of the α subunits of the heterotrimeric guanine nucleotide regulatory proteins Gi, Go, and Gt. This prevents the G protein heterotrimers from interacting with receptors, thus blocking their coupling and activation. Since the Gα subunits remain in their GDP-bound, inactive state, they are unable to inactivate adenylyl cyclase or open K+ channels. | [storage]
Store at +4°C | [Purification Methods]
Purify the toxin by stepwise elution from 3 columns comprising Blue Sepharose, Phenyl Sepharose and hydroxylapatite, and the purity is checked by SDS-PAGE. [Svoboda et al. Anal Biochem 159 402 1986, Biochemistry 21 5516 1982, Biochem J 83 295 1978.] |
