Abstract: Cytochrome c oxidase is the key player in cellular respiration, catalysing the reduction of molecular oxygen to water via its internal heme and copper redox centres. Biogenesis of the enzyme is a complex process involving up to 30 accessory proteins in higher eukaryotes. Factors directly involved in cofactor recruitment and insertion into the two core structural subunits I and II are also present in many bacteria and have been conserved during evolution. Herein we briefly review the chaperones required during early biogenesis steps, with special emphasis on the bacterial counterparts.
