magnesium:sodium antiporter activity

Catalysis of the reaction: Na+(in) + Mg2+(out) = Na+(out) + Mg2+(in).

obsolete sodium-transporting two-sector ATPase activity

OBSOLETE. Catalysis of the reaction: ATP + H2O + Na+(in) = ADP + phosphate + Na+(out).

obsolete isoleucine/valine:sodium symporter activity

OBSOLETE. Catalysis of the reaction: (isoleucine or valine)(out) + Na+(out) = (isoleucine or valine)(in) + Na+(in).

obsolete sodium:dicarboxylate/tricarboxylate symporter activity

OBSOLETE. Catalysis of the reaction: (dicarboxylate or tricarboxylate)(out) + Na+(out) = (dicarboxylate or tricarboxylate)(in) + Na+(in).

obsolete threonine/serine:sodium symporter activity

OBSOLETE. Catalysis of the reaction: (threonine or serine)(out) + Na+(out) = (threonine or serine)(in) + Na+(in).

obsolete glutamate/aspartate:sodium symporter activity

OBSOLETE. Catalysis of the reaction: (glutamate or aspartate)(out) + Na+(out) = (glutamate or aspartate)(in) + Na+(in).

obsolete hydrogen-/sodium-translocating ATPase activity

OBSOLETE. Catalysis of the reaction: ATP + H2O + (Na+ or H+)(in) = ADP + phosphate + (Na+ or H+)(out).

sodium ion binding

Binding to a sodium ion (Na+).

obsolete sodium-translocating V-type ATPase activity

OBSOLETE. Catalysis of the reaction: ATP + H2O + Na+(in) = ADP + phosphate + Na+(out). Found in vacuoles of eukaryotes and in bacteria.

obsolete betaine/GABA:sodium symporter activity

OBSOLETE. Catalysis of the reaction: (betaine or gamma-aminobutyric acid)(out) + Na+(out) = (betaine or gamma-aminobutyric acid)(in) + Na+(in).
