KEGG   ENZYME: 3.6.3.15Help
Entry
EC 3.6.3.15                 Enzyme                                 
Name
Na+-transporting two-sector ATPase
Class
Hydrolases;
Acting on acid anhydrides;
Acting on acid anhydrides to catalyse transmembrane movement of substances
BRITE hierarchy
Sysname
ATP phosphohydrolase (Na+-transporting)
Reaction(IUBMB)
ATP + H2O + Na+in = ADP + phosphate + Na+out [RN:R00086]
Reaction(KEGG)
Substrate
ATP [CPD:C00002];
H2O [CPD:C00001];
Na+ [CPD:C01330]
Product
ADP [CPD:C00008];
phosphate [CPD:C00009];
Na+ [CPD:C01330]
Comment
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+.
