Abstract

Subcellular vesicles of Vibrio alginolyticus hydrolyze ATP and accumulate Na+ in an ATP-dependent fashion. The Na+ uptake is (i) strongly stimulated by delta psi-discharging agents, i.e., the protonophorous uncoupler CCCP or valinomycin + K+ and (ii) arrested by DCCD at a concentration strongly inhibiting ATP hydrolysis. Lower concentrations of DCCD stimulate the Na+ accumulation supported by ATP hydrolysis as well as by NADH oxidation. It is concluded that there is an electrogenic DCCD-sensitive Na+-ATPase in the cytoplasmic membrane of V. alginolyticus.
