Sodium (Na+)-pumping F-type ATPase. ATPase activity is stimulated by Na+ (Wiangnon et al. 2007), and Na+ transport in liposomes has been demostrated (Soontharapirakkul and Incharoensakdi 2010). The enzyme appears to play a role in salt tolerance (Soontharapirakkul et al. 2011). This halotolerant cyanobacterium has both a Na+- and a H+-pumping ATPase (see TC# 3.A.2.1.10). The sequence of the δ-subunit was not available at the time of entry.
