phage endolysin [Escherichia coli O157:H7 str. Sakai]

Protein Classification

lysozyme( domain architecture ID 13014134)

lysozyme, also called endolysin or muramidase, hydrolyzes (1->4)-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrins

endolysin R21-like proteins; Unlike T4 E phage lysozyme, the endolysin R21 from Enterobacteria phage P21 has an N-terminal SAR (signal-arrest-release) domain that anchors the endolysin to the membrane in an inactive form, which act to prevent premature lysis of the infected bacterium. The dsDNA phages of eubacteria use endolysins or muralytic enzymes in conjunction with hollin, a small membrane protein, to degrade the peptidoglycan found in bacterial cell walls. Similarly, bacteria produce autolysins to facilitate the biosynthesis of its cell wall heteropolymer peptidoglycan and cell division. Endolysins and autolysins are found in viruses and bacteria, respectively. Both endolysin and autolysin enzymes cleave the glycosidic beta 1,4-bonds between the N-acetylmuramic acid and the N-acetylglucosamine of the peptidoglycan.

 9-170 2.13e-16

P1 lysozyme Lyz-like proteins; Enterobacteria phage P1 lysozyme Lyz is secreted to the Escherichia coli periplasm where it is membrane bound and inactive. Activation involves the release from the membrane, an intramolecular thiol-disulfide isomerization and extensive structural rearrangement of the N-terminal region. The dsDNA phages of eubacteria use endolysins or muralytic enzymes in conjunction with hollin, a small membrane protein, to degrade the peptidoglycan found in bacterial cell walls. Similarly, bacteria produce autolysins to facilitate the biosynthesis of its cell wall heteropolymer peptidoglycan and cell division. Endolysins and autolysins are found in viruses and bacteria, respectively.
