H(+)-ATP synthase is a multisubunit membrane-bound enzyme complex consisting of an F0 segment embedded in the membrane and an F1 segment attached to the F0. The F1 segment provides the catalytic activity for the interconversion of ADP and ATP, whereas the F0 segment contains a proton channel that couples the transmembrane H+ gradient and membrane potential generated by electron transport to the synthesis of ATP in the F1 domain.
