Comparison of the TCA cycle in a MS2 phage-infected Escherichia coli cell with an uninfected Escherichia coli cell. Most of the reactions were downregulated by four to six folds and some of them were even deactivated. (A) Schematic representation of the TCA cycle. Words in red represent metabolites. Rectangular boxes represent reactions, the key for which is provided in the Table 2. The numbers in the circle represent the flux values of the corresponding reactions in uninfected cell (top value) and infected cell (bottom value). (B) Quantitative representation of variation in the uninfected and infected cell fluxes of the TCA cycle. Key to the x-axis labels is given in the Table 2.
