In mitochondria, ATP synthase complexes are arranged in rows of dimers along the edges of the cristae [1] [2] [3] [4] [5]. Our aim is to define the structural roles of subunits e, f, g, DAPIT, 6.8PL and ATP8 in the dimerisation of monomeric complexes and in the linking of dimers together into long rows on the cristae edges. [6] [7] [8] [9] [5]. It has been proposed that the mitochondrial permeability transition pore is associated with dimers of ATP synthase [10], but we can find no evidence to support this proposition (see here).
