Web11 apr. 2024 · Bacteria complete cell division by splitting the division septum, a process that requires the regulated activity of peptidoglycan hydrolases. Here, Staphylococcus aureus divisome protein FtsK is shown to regulate daughter cell splitting by stabilizing the peptidoglycan hydrolase Sle1 and promoting its preferential septal export. The … WebBakterien haben eine Vielzahl von Membranmodifikationen entwickelt, wie z.
