A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

About

Bacterial cell shape is physically deteScreen Shot 2015-08-03 at 5.24.58 PMrmined by the peptidoglycan cell wall. Within this project we study the enzymatic remodeling of the bacterial cell wall using live-cell high-resolution microscopy. We study the motion of enzymes and other proteins such as the bacterial cytoskeleton MreB and the incorporation of new material into the cell wall. The dynamics and localization of these molecules informs us about their activities and the mode of cell-wall expansion. Experiments are combined with image analysis and modeling in order to deduce the underlying principle of how bacteria maintain and regulate their cell shapes.
