Abstract

Accumulating evidence indicates that the enzymes involved in mitochondrial oxidative phosphorylation (OXPHOS) are co-assembled into higher-ordered supercomplexes within the mitochondrial inner membrane. This review will focus largely on the OXPHOS supercomplexes of the yeast Saccharomyces cerevisiae. The recent evidence to indicate that diversity in the populations of the cytochrome bc 1-COX supercomplexes exist shall be outlined. In addition, the existence of dimeric/oligomeric F1Fo-ATP synthase complexes and their proposed role in establishment of the cristae architecture of the inner mitochondrial membrane shall also be discussed.
