13C-incorporation during the switch from 12CH4 to 13CH4 in Methylosinus trichosporium OB3b. (A) 12C/13C-isotopomer distributions of serine (A), glycine (B), 3-hydroxybutyric acid (C), propionyl-CoA (D), acetyl-CoA (E), malate (F), phosphoenolpyruvate (G), aspartic acid (H), alanine (I), and succinate (J). Additional data are shown in Figure A1 in Appendix. M + 0 represented non-labeled compound, M + 1 represented compound with one 13C-label, M + 2 represented compound with two 13C-labels and so on.
