Fig. 6.

Central carbon and γ-PGA production pathways of B. subtilis. The central carbon pathway that includes the pathway of glycolysis (blue), the pentose phosphate pathway (yellow) and the TCA cycle (red) is represented. The pathway of acetate (dark gray) and γ-PGA (green) biosynthesis are also represented. Dashed thin arrows indicate the bypass pathway from akg to succ, with sucsal as intermediate metabolite. The green arrow with dashed edge indicates a set of reactions (not shown) converting akg into glu-L. Metabolite and reaction names are reported in lower and upper case, respectively, according to the annotation used in the original model
