Reaction: ATP + H2O + Na+in = ADP + phosphate + Na+out
Systematic name: ATP phosphohydrolase (Na+-transporting)
Other name: ATP synthase; vacuolar-type Na+-ATPase; Na+-translocating ATPase; Na+-translocating F1Fo-ATPase; vacuolar-type Na+-translocating ATPase
Comments: A multisubunit non-phosphorylated ATPase that is involved in the transport of ions. An enzyme found in alkaliphilic bacteria that is similar to EC 3.6.3.14 (H+-transporting two-sector ATPase) where Na+ replaces H+.
