<Tr> <Td> epsilon </Td> <Td> ATP5E </Td> </Tr> <P> Fo is a water insoluble protein with eight subunits and a transmembrane ring . The ring has a tetramer shape with a helix loop helix protein that goes though conformational changes when protonated and deprotonated, pushing neighboring subunits to rotate, causing the spinning of F which then also affects conformation of F, resulting in switching of states of alpha and beta subunits . The F region of ATP synthase is a proton pore that is embedded in the mitochondrial membrane . It consists of three main subunits a, b, and c, and (in humans) six additional subunits, d, e, f, g, F6, and 8 (or A6L). An atomic model for the dimeric yeast F region was determined by cryo - EM at an overall resolution of 3.6 Å </P> <Table> F - Main subunits <Tr> <Th> Subunit </Th> <Th> Human Gene </Th> </Tr> <Tr> <Td> </Td> <Td> ATP6 </Td> </Tr> <Tr> <Td> </Td> <Td> ATP5F1 </Td> </Tr> <Tr> <Td> </Td> <Td> ATP5G1, ATP5G2, ATP5G3 </Td> </Tr> </Table> <Tr> <Th> Subunit </Th> <Th> Human Gene </Th> </Tr>
