Aphanothece halophytica is a halotolerant alkaliphilic cyanobacterium that can grow in media of up to 3.0 m NaCl and pH 11. Here, we show that in addition to a typical H(+)-ATP synthase, Aphanothece halophytica contains a putative F(1)F(0)-type Na(+)-ATP synthase (ApNa(+)-ATPase) operon (ApNa(+)-atp). The operon consists of nine genes organized in the order of putative subunits β, ε, I, hypothetical protein, a, c, b, α, and γ. Homologous operons could also be found in some cyanobacteria such as… CONTINUE READING
