Purification of pertussis toxin substrates from bovine heart membranes.
Pertussis toxin substrates were purified from bovine heart membranes by means of a sequential column chromatographic techniques. The elution pattern from the final ion-exchange chromatography and relative mobilities of these peptides on SDS-polyacrylamide gel electrophoresis revealed that the bovine heart membranes contained two distinct pertussis toxin substrates: Gi2 and Go.
