Figure 7From: Algorithms for computing parsimonious evolutionary scenarios for genome evolution, the last universal common ancestor and dominance of horizontal gene transfer in the evolution of prokaryotesRepresentation of essential metabolic pathways in different versions of LUCA: glycolysis and gluconeogenesis. The enzyme names are accompanied by COG numbers and gene names (from E. coli unless indicated otherwise: PH, Pyrococcus horikoshii, BS, Bacillus subtilis). Phyletic patterns for all COGs are shown using the species abbreviations listed in the legend to Fig. 5. The COGs appearing in different reconstructed versions of LUCA are color-coded in this figure and Figures 7,8,9,10,11: LUCA0.9, yellow; LUCA1.0, green; LUCA1.5, blue; LUCA2.0 purple; LUCA3.0, red.Back to article page
