Reconstitution of the Fo complex of Escherichia coli ATP synthase from isolated subunits. Varying the number of essential carboxylates by co-incorporation of wild-type and mutant subunit c after purification in organic solvent.

Abstract excerpt

Subunit c of the Escherichia coli F1F0-ATPase, purified in chloroform/methanol (2:1), was reconstituted with detergent-solubilized F0 subunits a and b to form a functionally active H+ channel. The rates of H+ uptake by the proteoliposomes containing the reconstituted F0 complex were comparable to those observed with native F0 reconstituted without subunit dissociation. The F0 reconstituted from purified subunits...
