Abstract

The ADP-ribosylation of GTP-binding proteins (G-proteins) catalyzed by pertussis toxin was inhibited by endogenous inhibitor activity in the membrane extract of bovine brain. Most of the activity appeared in the fractions eluted from a DEAE-Sephacel column by 0.5 M NaCl. The activity was heat-stable and sensitive to pronase K. The results suggest the presence of an endogenous inhibitor of pertussis toxin in bovine brain.
