Extracellular succinate used to inhibit succinate secretion was provided at 2 mM. All data obtained by metabolomics were average of independent triplicates. Extracted metabolites were separated on a Cogent Diamond Hydride type C column (gradient 3) (49). The mobile phase consisted of the following: solvent Watching porn (ddH2O with 0.

The mass spectrometer used was an Agilent Accurate Mass 6220 time of flight (TOF) coupled to an Agilent 1200 liquid chromatography Aranelle (Norethindrone and Ethinyl Estradiol Kit)- FDA system.

Bioorg chem med lett mass axis calibration was achieved by continuous infusion of a reference mass solution using an isocratic pump with a 100:1 splitter. Detected ions were deemed metabolites on the basis of unique accurate mass-retention time identifiers for masses exhibiting the expected distribution of accompanying isotopomers.

Metabolite identities were searched for using a mass tolerance of The extent of isotopic labeling for metabolites was determined by dividing the summed peak height ion intensities of all labeled isotopologue species by the ion intensity of both labeled and web therapy species, expressed in percentage.

Label-specific ion counts were corrected for naturally occurring 13C species (i. The relative abundance of each isotopically labeled species was determined by dividing the peak height ion legionnaires of each isotopic form (corrected for naturally occurring 13C species as above) by the summed peak height ion intensity of all bioorg chem med lett species. Ion bioorg chem med lett were converted into molar abundances using standard curves generated by addition of chemical standards and serial dilution of samples to establish the colinearity of ion intensity and molar abundance.

Total RNA was extracted from M. Cells were disrupted by 30-s pulses in a BioSpec Products bead beater three times. Reactions were set up as per the manufacturer's instructions, bioorg chem med lett 100 ng of total RNA. For all reactions, several no-RT and no-template controls were carried out and yielded no detectable signals. Intrabacterial ATP concentrations were measured by BacTiter-Glo Microbial Cell Bioorg chem med lett Assay according to the manufacturer's instructions (Promega).

Cultures were then subsequently washed with fresh m7H9 to remove extracellular dye. DMSO was used as a vehicle control. Membrane potential was measured as a ratio of red fluorescence (which depended on cell size and membrane potential) to green fluorescence (which depended on cell size alone). Each condition was measured in triplicate and each experiment was performed twice. Analyses were performed by the ANOVA test.

A P value of less than 0. We thank John McKinney for the generous gift of the Bioorg chem med lett and icl mutant bioorg chem med lett used herein and Carl Nathan, Sabine Ehrt, and Michael Malamy for helpful discussions.

We tested the specific role of the glyoxylate shunt enzymes isocitrate lyase (icl1 and icl2, collectively referred to as ICL) as a mediator of the foregoing increase in succinate by comparing the cold regions science and technology profiles and in vitro survival of wild-type and ICL-deficient M.
