Figure 2

Metabolic flux distributions based on the genome-scale metabolic model. Metabolic flux distribution for the iAF1260-3HP (A), Δzwf (B), ΔtpiA (C), and ΔtpiA Δzwf (D) models are shown. Flux values are normalized by the glycerol uptake rate to 100%. Width of the black arrow corresponds to the relative flux value of glycerol uptake rate. Gray arrow indicates the flux of the corresponding reaction was 0.
