Intracellular levels of nucleoside triphosphates and UDP-carbohydrate of rpoB mutant and its mutation-repaired strain. Relative values of GTP, ATP, CTP, and UTP, and relative abundances of UDP-Glu/Gal and UDP-GlcNAc of JMUB217-derived mutant (rpoB2) and its mutation-repaired strain (rpoB2-repair). Mean values of intracellular metabolites of mutant/mutation-repaired strains were compared with that of wild type via one-way ANOVA. *P < 0.05, **P < 0.01, and ***P < 0.001. Figure 6 was constructed using metabolomics data different from Fig. 3 to 5 and Fig. S1.
