title: [Sodium pump reconstruction in lipid vesicles].
abstract: Reconstitution of purified lubrol-solubilized preparation of Na,K-ATPase from the calf brain was performed in liposomes and transport characteristics of this system were investigated. The system was demonstrated to preserve vectoral features of the sodium pump. Addition of ATP to the medium evoked active influx of sodium and efflux of rubidium in proteoliposomes. Ouabain inhibited transport processes when enclosed into proteoliposomes, i.e. from the side opposite to the ATP-sensitive one.
