  1. *Predictions of the number of mitochondrial proteins are from sequence homology, targeting sequences, phylogenetic profiling or extrapolation from a set of experimental values. †Prediction percentage: the percentage of genes in the genome predicted to encode mitochondrial proteins from targeting analyses or phylogenetic profiles; ‡Extrapolated: the total number of mitochondrial proteins predicted from the percentage value given and the genome size of each organism. §Experimental percentage: the percentage of the predicted proteome found in experimentally determined mitochondrial proteomes.
