Nettet22. jun. 2016 · Double-strand DNA bacteriophages employ the holin–endolysin dyad as core components of different strategies to lyse bacterial hosts. In the so-called canonical model the holin holes play an essential role in lysis as they provide a conduit for passage of the cytoplasm-accumulated endolysin to the cell wall (CW), where it degrades the … Nettet6. jun. 2024 · During the phage life cycle, when sufficient level of endolysin has accumulated in the cell, holin is expressed and inserted into the cytoplasmic membrane, which disrupts the membrane in the cell. Finally, endolysin degrades the bacterial cell wall, leading to hypotonic cell lysis.
