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

Abstract:

Bacterial cell division is a highly regulated process, coordinated by a multi-protein complex called the divisome. The assembly of the divisome is initiated by FtsZ, the bacterial tubulin homologue, which polymerizes to form a Z-ring at the future site of septation. Subsequently, late divisomal proteins are recruited in a largely linear hierarchy to assemble the complex transmembrane machinery required for septal cell wall remodeling, constriction and final separation of the daughter cells. The molecular mechanisms of this assembly and their regulation remain largely unknown, especially in Corynebacteriales, a bacterial suborder comprising important human pathogens such as, Mycobacterium tuberculosis and Corynebacterium diphtheriae. The main objective of my work is to identify and characterize the protein-protein interactions involved in the assembly and regulation of the division machinery in Corynebacteriales using an integrative biology approach, ranging from structural biology to bacterial genetics and cellular biology.
