Itaconic acid | itaconic acid specifically inhibits growth of wild-type cells on acetate and propionate, but not dextrose, in an ICL-dependent manner, and elicited metabolomic changes similar to those observed with ICL-deficient cells. Enzyme ICL inhibition by itaconic acid results in a specific decrease in intrabacterial pH from pH 7.3 to pH 6.4 in propionat-grown cells, not in acetate-grown cells | Mycobacterium tuberculosis |

malfunction | absence of MCL activity results in the accumulation of methylisocitrate as a metabolic dead end product arising from the stoichiometric consumption of oxaloacetate by propionyl-CoA, phenotype, overview. Isocitrate lyases are essential for survival on both acetate and propionate because of its methylisocitrate lyase activity. Lack of methylisocitrate lyase activity converts the cell methylcitrate cycle into a dead end pathway that sequesters tricarboxylic acid (TCA) cycle intermediates into methylcitrate cycle intermediates, depletes gluconeogenic precursors, and results in defects of membrane potential and intrabacterial pH | Mycobacterium tuberculosis |
