In E. coli, H+-transporting F1Fo ATP synthases are found embedded in the inner membranes, and consist of two structurally and functionally distinct sectors, termed F1 and Fo. The F1 sector contains the catalytic sites for ATP synthesis. The Fo sector spans the membrane and in E. coli consists of three subunits in an a1b2c10 ratio.
