7.2.2.3

P-type Na⁺ transporter

ATP + H₂O + Na⁺_{[side 1]} = ADP + phosphate + Na⁺_{[side 2]}

Na⁺-exporting ATPase (ambiguous), ENA1 (gene name), ENA2 (gene name), ENA5 (gene name), sodium transport ATPase (ambiguous), sodium-translocating P-type ATPase

ATP phosphohydrolase (P-type, Na⁺-exporting)

A P-type ATPase that undergoes covalent phosphorylation during the transport cycle. This enzyme from yeast is involved in the efflux of Na⁺, with one ion being exported per ATP hydrolysed. Some forms can also export Li⁺ ions. cf. EC 7.2.2.1, Na⁺-transporting two-sector ATPase and EC 7.2.2.4, ABC-type Na⁺ transporter.
