Figure 4.
Overexpression of PknB_PASTA results in alteration of bacterial morphology and vancomycin labelling. Mycobacteria from logarithmic growth phase were labelled with Vancomycin-BODIPY conjugate, washed and mounted in PBS and examined using a Diphot 300 inverted microscope. Three independent fields for each strain are shown. Bars indicate 5 μm. (a) MIND and (b) TMP. Left panel, phase contrast; middle panel, fluorescence microscopy; right panel, merged images. Arrows indicate labelled peptidoglycan.
