Enzyme Information
| 7.2.2.1 |
Na(+)-transporting two-sector ATPase.
based on mapping to UniProt Q08636
ATP + H(2)O + n Na(+)(Side 1) = ADP + phosphate + n Na(+)(Side 2).
-!- A multisubunit ATPase transporter found in some halophilic or alkalophilic bacteria that functions in maintaining sodium homeostasis. -!- The enzyme is similar to EC 7.1.2.2 but pumps Na(+) rather than H(+). -!- Cf. EC 7.2.2.3 and EC 7.2.2.4. -!- Formerly EC 3.6.3.15.
