  2. Lysin - Wikipedia

    en.wikipedia.org/wiki/Lysin

    Double-stranded DNA phage lysins tend to lie within the 25 to 40 kDa range in terms of size. A notable exception is the streptococcal PlyC endolysin, which is 114 kDa. PlyC is not only the biggest and most potent lysin, but also structurally unique since it is composed of two different gene products, PlyCA and PlyCB, with a ratio of eight PlyCB subunits for each PlyCA in its active conformation.

  3. Enzybiotics - Wikipedia

    en.wikipedia.org/wiki/Enzybiotics

    Endolysins are specialized enzymes derived from bacteriophages, viruses that infect bacterial cells in order to replicate within them. Because phages have coevolved with their bacterial hosts, the endolysin system is very efficient at degrading bacterial cell walls. [3]

  4. Bacteriophage - Wikipedia

    en.wikipedia.org/wiki/Bacteriophage

    A bacteriophage (/ b æ k ˈ t ɪər i oʊ f eɪ dʒ /), also known informally as a phage (/ ˈ f eɪ dʒ /), is a virus that infects and replicates within bacteria and archaea. The term is derived from Ancient Greek φαγεῖν (phagein) 'to devour' and bacteria .

  5. Lytic cycle - Wikipedia

    en.wikipedia.org/wiki/Lytic_cycle

    The virions self-assemble from these components, with the first virion appearing at about 20 min after infection. The fourth pathway is for lysis. In lambda 5 proteins are involved in lysis: the holin and antiholin from gene S, the endolysin from gene R and the spanin proteins from genes Rz and Rz1. In wild-type lambda, lysis occurs at about 50 ...

  6. T4 holin - Wikipedia

    en.wikipedia.org/wiki/T4_holin

    Although the endolysin of phage T4 encoded by the e gene (Lysozyme E) was identified in 1961, the holin (product of gene t and called T-holin) was not characterized until 2001. [1] A representative list of proteins belonging to the T4 holin family can be found in the Transporter Classification Database .

  7. Phage therapy - Wikipedia

    en.wikipedia.org/wiki/Phage_therapy

    Phage therapy is the use of bacteriophages to treat bacterial infections. Bacteriophage treatment offers a possible alternative to conventional antibiotic treatments for bacterial infection. [55] It is conceivable that, although bacteria can develop resistance to phages, the resistance might be easier to overcome than resistance to antibiotics.

  8. Lambda phage - Wikipedia

    en.wikipedia.org/wiki/Lambda_phage

    R is an endolysin, an enzyme that escapes through the S holes and cleaves the cell wall. Rz and Rz1 are membrane proteins that form a complex that somehow destroys the outer membrane, after the endolysin has degraded the cell wall. For wild-type lambda, lysis occurs at about 50 minutes after the start of infection and releases around 100 virions.

  9. Actinobacterial phage holin family - Wikipedia

    en.wikipedia.org/wiki/Actinobacterial_phage...

    Mycobacteriophage Ms6 is a double-stranded DNA (dsDNA) bacteriophage which, in addition to the predicted endolysin (LysA)-holin (Gp4) lysis system, encodes three additional proteins within its lysis module: Gp1, LysB, and Gp5. [2] Ms6 Gp4 (TC# 1.E.18.1.2) was previously described as a class II holin-like protein.
