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

During infection of their hosts, Gram-positive bacteria express surface proteins that serve multiple biological functions. Surface proteins harbouring a C-terminal sorting signal with an LPXTG motif are covalently linked to the cell wall peptidoglycan by a transamidase named sortase. Two genes encoding putative sortases, termed srtA and srtB, were identified in the genome of the intracellular pathogenic bacterium Listeria monocytogenes. Inactivation of srtA abolishes anchoring of the invasion protein InlA to the bacterial surface. It also prevents the proper sorting of several other peptidoglycan-associated LPXTG proteins. Three were identified by a mass spectrometry approach. The DeltasrtA mutant strain is defective in entering epithelial cells, similar to a DeltainlA mutant. In contrast to a DeltainlA mutant, the DeltasrtA mutant is impaired for colonization of the liver and spleen after oral inoculation in mice. Thus, L. monocytogenes srtA is required for the cell wall anchoring of InlA and, presumably, for the anchoring of other LPXTG-containing proteins that are involved in listerial infections.
