Intersubunit bridging by Na(+) ions as a rationale for the unusual stability of the c-rings of Na(+)-translocating F(1)F(0) ATP synthases
The oligomeric c-rings of Na(+)-translocating F(1)F(0) ATP synthases exhibit unusual stability, resisting even boiling in SDS. Here, we show that the molecular basis for this remarkable property is intersubunit crossbridging by Na(+) or Li(+) ions. The heat stability of c(11) was dependent on the pr...
