表面层(S层)是在所有古细菌和大多数细菌细胞周围形成的保护性蛋白质外壳。艰难梭菌是革兰氏阳性细菌,其肽聚糖细胞壁覆盖有S层。C中的S层。艰难梭菌主要由S层蛋白A(SlpA)构成,SlpA是关键的毒力因子,是疾病的绝对必需品。S层生物发生是一个复杂的多步骤过程,其破坏对细菌具有严重后果。我们研究了SlpA分泌和S-层生长的亚细胞定位;观察在与细胞壁合成一致的特定位点处S-层的形成,而SlpA从细胞的分泌是相对离域的。我们的结论是,这种离域分泌的SlpA导致池的前体细胞壁中,这是可用于修复在细胞生长过程中形成的S-层中的开口或以下的损害。
Surface layers (S-layers) are protective protein coats which form around all archaea and most bacterial cells.Clostridium difficileis a Gram-positive bacterium with an S-layer covering its peptidoglycan cell wall. The S-layer inC. difficileis constructed mainly of S-layer protein A (SlpA), which is a key virulence factor and an absolute requirement for disease. S-layer biogenesis is a complex multi-step process, disruption of which has severe consequences for the bacterium. We examined the subcellular localization of SlpA secretion and S-layer growth; observing formation of S-layer at specific sites that coincide with cell wall synthesis, while the secretion of SlpA from the cell is relatively delocalized. We conclude that this delocalized secretion of SlpA leads to a pool of precursor in the cell wall which is available to repair openings in the S-layer formed during cell growth or following damage.
