WebMar 22, 2012 · Computational predictions and analyses of HolSMP. The complete 36,126-bp sequence of phage SMP has 48 open reading frames (ORF). ORF42, designated LySMP, encodes the putative endolysin.ORF43, which is 429 bp long and upstream of the lySMP gene, is predicted to encode a putative holin protein, designated HolSMP (Figure … WebIn an event that defines the end of the vegetative cycle, the lambda holin S acts suddenly to permeabilize the membrane. This permeabilization enables the R endolysin to attack the cell wall, after which cell lysis occurs within seconds. A C-terminal fusion of the R endolysin with full-length beta-galactosidase (beta-Gal) was tested for lytic ...

WebJul 1, 2013 · An unusual and remarkable different class of holin-endolysin systems has arisen in recent years (Park et al., 2006, 2007). This class, represented by the lambdoid bacteriophage 21, employs endolysins having N-terminal SAR domains and pinholins. For phages encoding SAR endolysins it has been shown that the holin protein needs only to … WebAug 1, 2024 · The endolysin from phage P335 (LysP335) was associated with a class II holin and has a more complex structure. LysP335 has an N-terminal predicted secretion signal composed of a TMD followed by a GH25_Cpl1-like domain with predicted glucosamidase activity and 2 C-terminal LysM CBDs.
WebDuring the release of their progeny, enzymes related to the lytic mechanism are used to lyse the bacterial host; members of the classical holin-endolysin lysis system have been found in many phages . Endolysins can be divided into five main classes [ 46 ]; one of them comprises the endopeptidases, also known as endolysins or peptidoglycan ...
