Web1 iun. 2009 · Direct phage–nonhomologous ‘host’ contact was not required for inhibition. Lysates of øC2(W) contained a phage-induced lysin. Evidence is presented that the inhibitory effect of øC2(W) against paired and multi-strain cultures is due to the lysis of phage-insensitive strains by phage lysin. WebAn example is the use of the phage protein bacterial cell wall lysin of a phage commonly targeting methicillin-resistant S. aureus (MRSA), which elicits a potent immune response and subsequently ...
WebLysin A protein that degrades the cell wall and aids in the release of phage particles from an infected cell. These proteins are multi-domain and highly mosaic within the mycobacteriophages. Mycobacteriophages frequently have two lysins: Lysin A and Lysin B. A lysogenic bacterial cell Lysogen A lysogen is a bacterium carrying a prophage.
