Measurement of sugar nucleotides in the TbUAP conditional null mutant under permissive and nonpermissive conditions. Representative liquid chromatography-tandem mass spectrometry chromatograms of sugar nucleotides extracted from the TbUAP conditional null mutant before (A) and after (B) withdrawal of tetracycline for 48 h. The upper chromatogram in each panel shows the peaks corresponding to GDP-Man and the GDP-Glc internal standard, and the lower chromatogram shows the peak corresponding to UDP-GlcNAc.
