Figure 28: Metabolic pathways showing levels of enzymes (or proteins) and intracellular metabolite concentrations in the fadR mutant E. coli relative to those in the parent at the exponential phase grown in glucose minimal medium under aerobic condition. The numbers beside the protein names and the metabolites represent the ratios. Shaded and boxed metabolites mean increased and decreased intracellular concentrations in fadR mutant E. coli.
