The membrane sector of vacuolar H(+)-ATPase by itself is impermeable to protons.

Acta physiologica Scandinavica. Supplementum - 1 Jan 1992

Beltrán C, Nelson N

Abstract excerpt

The sensitivity for vanadate of proton uptake activities of isolated chromaffin granules and yeast vacuoles was investigated. About 0.5 mM vanadate caused 50% inhibition of ATP-dependent proton uptake activity in both membranes. The proton conductivity across chromaffin granule membranes and yeast vacuoles was assayed in the presence and absence of the catalytic sectors of their respective V-ATPases. Removal of...
