Endolysin regulation in phage mu lysis
Did you know?
WebIn general, endolysins from phages of Gram-negative hosts are smaller with a single domain responsible for both binding and catalysis of the PG. In contrast, phages infecting Gram-positive bacteria produce endolysins with the cell-wall-binding domain separated from the catalytic domain. WebIn sum, these studies proposed new models for lysis regulation. In T4, the current model for LIN involves the stabilization of a complex of three proteins in two compartments of …
WebLarge phages elaborate an enzyme ("endolysin") to degrade the cell wall and also a small membrane protein ("holin"). The holin accumulates in the membrane and then, at a precisely scheduled time, suddenly forms a hole to allow release of endolysin through the cytoplasmic membrane to gain access to the wall. ... small phages blocks a different ... WebYoung, Ryland - Texas A&M University (TAMU) Scholar profile, educations, publications, research, grants, awards, courses, concepts, and topics. Most bacterial viruses (phages) cause lysis of their host cell to release the progeny virions. Large phages elaborate an enzyme ("endolysin") to degrade the cell wall and also a small membrane …
WebJan 1, 2024 · In Gram-negative hosts, lysis requires proteins that disrupt each of the three cell envelope components, only one of which has been identified in Mu: the endolysin gp22. We show that gp22 can be characterized as a SAR endolysin, a muralytic enzyme that activates upon release from the membrane to degrade the cell wall. WebThe first steps in phage lysis involve a temporally controlled permeabilization of the cytoplasmic membrane followed by enzymatic degradation of the peptidoglycan. For Caudovirales of Gram-negative hosts, there are two different systems: the holin-endolysin and pinholin-SAR endolysin pathways.
