| description | The b subunit of the E. coli F-type ATP synthase is present as a dimer and links the peripheral F(1) subunits to the membrane-integral F(0) portion. The dimerisation domain of the b subunit consists of an α-helical coiled-coil structure. In the dimer the two helices form a coiled coil with a right-handed superhelical twist. Analysis of b sequences from other prokaryotes indicates conservation of an undecad repeat in this domain []. This superfamily represents a membrane domain that covers most of the dimerisation domain of the b subunit of the E. coli F-type ATP synthase. |
