Fig. 4From: Elucidation of the roles of adhE1 and adhE2 in the primary metabolism of Clostridium acetobutylicum by combining in-frame gene deletion and a quantitative system-scale approachVenn diagrams of representative genes with involved pathways, which matched the significance criteria (>4-fold increase or decrease) in the ΔadhE1 and ΔadhE2 mutants. A complete list of each metabolic condition is provided in the Additional file 2 Back to article page
