General Information

General Information Comment Organism
physiological function the assembly and activity of cytochrome c oxidase is dependent on the availability of heme A, one of its essential cofactors. In eukaryotes, two inner mitochondrial membrane proteins, heme O synthase (Cox10) and heme A synthase (Cox15), are required for heme A biosynthesis. The two physiological partners do not share the same regulatory mechanism. The stoichiometry between Cox15 and Cox10 is 8:1, not 1:1 as it has generally been assumed Saccharomyces cerevisiae
