Figure 5From: Non-homologous isofunctional enzymes: A systematic analysis of alternative solutions in enzyme evolutionDependence between the genome size (the total number of encoded proteins) and the number of encoded enzymes. A. The total number of encoded enzymes with assigned four-digit EC numbers. B. The number of encoded non-homologous isofunctional enzymes. Prokaryotic genomes are indicated with diamonds, eukaryotic genomes are indicated with squares. The best fit lines were calculated separately for prokaryotes (blue) and eukaryotes (red).Back to article page
