Comparison of i CM925 with the Senger & Papoutsakis C. acetobutylicum model. The number, database distribution, and pathway distribution of reactions in i CM925 and the Senger & Papoutsakis C. acetobutylicum model were compared based on KEGG IDs. (A) Numbers of reactions in common between the two models or unique to each are depicted by bars on the graph. The fractions of unique and shared reactions that are active in i CM925 are denoted by light-shaded regions. (B) The database distribution of reactions exclusive to i CM925 are shown in the upper left, while the pathway distribution is shown in the bottom of the panel.
