. "A sodium ion-transporting two-sector ATPase complex that couples ATP hydrolysis to the transport of sodium ions across a concentration gradient. The complex comprises a membrane sector (V0) that carries out proton transport and a cytoplasmic compartment sector (V1) that catalyzes ATP hydrolysis." . .
