| Abstract | This entry represents subunit F6 (or coupling factor 6) found in the F0 complex of F-ATPases in mitochondria. The F6 subunit is part of the peripheral stalk that links the F1 and F0 complexes together, and which acts as a stator to prevent certain subunits from rotating with the central rotary element. The peripheral stalk differs in subunit composition between mitochondrial, chloroplast and bacterial F-ATPases. In mitochondria, the peripheral stalk is composed of one copy each of subunits OSCP (oligomycin sensitivity conferral protein), F6, B and D [ 16045926]. There is no homologue of subunit F6 in bacterial or chloroplast F-ATPase, whose peripheral stalks are composed of one copy of the delta subunit (homologous to OSCP), and two copies of subunit B in bacteria, or one copy each of subunits B and Bż in chloroplasts and photosynthetic bacteria.
