Overview of catabolic pathways encoded by the A. saccharovorans genome. Substrates utilized are in boldface, enzymes and proteins encoded by genes identified on the genome are in blue, and energy-rich intermediate compounds are in red. Panels: A, utilization of carbohydrates; B, utilization of proteins; C, glycolysis (EM and ED pathways); D, pyruvate degradation; E, pentose phosphate synthesis; F, β-oxidation of long-chain fatty acids; G, formation of proton motive force coupled with ATP generation.
