NettetPhage lysins or endolysins are cell wall–hydrolyzing enzymes synthesized during late gene expression in the lytic cycle of multiplication of most phages, thereby enabling the release of progeny phages. The mechanisms of lysis are not equal for all phages and may even differ in the same bacterial host depending on the phage.

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.
