The antibiotics venturicidin, oligomycin and ossamycin were investigated as potential inhibitors of the Escherichia coli H+-ATPase. It was found that venturicidin strongly inhibited ATP-driven proton transport and ATP hydrolysis, while oligomycin weakly inhibited these functions. Inhibition of the H+-ATPase by venturicidin and oligomycin was correlated with inhibition of F0-mediate proton transport. Both inhibitors were found to interfere with the covalent reaction between dicyclohexyl[14C]carbodiimide and the F0 subunit c (uncE protein). Ossamycin had no direct inhibitory effect on E. coli F0 or F1; rather, it was found to uncouple ATP hydrolysis from proton transport.
