Purification and Biochemical Characterization of the Lambda Holin [PDF]

open access: yesJournal of Bacteriology, 1998
ABSTRACT Holins are small phage-encoded cytoplasmic membrane proteins, remarkable for their ability to make membranes permeable in a temporally regulated manner. The purification of S105, the λ holin, and one of the two products of gene S is described.

Mycobacteriophage D29 holin C‐terminal region functionally assists in holin aggregation and bacterial cell death [PDF]

open access: yesThe FEBS Journal, 2015
Holins are phage‐encoded small transmembrane proteins that perforate the bacterial cytoplasmic membrane. In most cases, this process allows the phage‐encoded peptidoglycan hydrolases to act on the cell wall, resulting in host cell lysis and phage release.

Phylogenetic relationships of the holins observed in lactococcal phages.

open access: yes, 2022
We investigated the diversity of holins found in 253 complete lactococcal phage genomes available in GenBank. ClustalW (v2.1) was used to perform multiple alignments and generate a phylogenetic tree (S7 Data).

Oligohistidine Tag Mutagenesis of the λ Holin Gene [PDF]

open access: yesJournal of Bacteriology, 1998
ABSTRACT Holins are a diverse group of small integral membrane proteins elaborated by bacteriophages to lyse bacterial hosts and effect release of progeny phages in a precisely timed manner. Recently, the holin S gene of phage λ was overexpressed and the holin protein was purified to homogeneity by means ...

Getting Outside the Cell: Versatile Holin Strategies Used by Distinct Phages to Leave Their Bacillus thuringiensis Host

open access: yes, 2022
Holins are small transmembrane proteins involved in the final stage of the lytic cycle of double-stranded DNA (dsDNA) phages. They cooperate with endolysins to achieve bacterial lysis, thereby releasing the phage progeny into the extracellular ...

Evidence for an Adaptation of a Phage-Derived Holin/Endolysin System to Toxin Transport in Clostridioides difficile

open access: yesFrontiers in Microbiology, 2018
The pathogenicity locus (PaLoc) of Clostridioides difficile usually comprises five genes (tcdR, tcdB, tcdE, tcdA, tcdC). While the proteins TcdA and TcdB represent the main toxins of this pathogen, TcdR and TcdC are involved in the regulation of their ...

Mycobacteriophage endolysins: diverse and modular enzymes with multiple catalytic activities. [PDF]

open access: yesPLoS ONE, 2012
The mycobacterial cell wall presents significant challenges to mycobacteriophages--viruses that infect mycobacterial hosts--because of its unusual structure containing a mycolic acid-rich mycobacterial outer membrane attached to an arabinogalactan layer ...

Prediction of Phage Virion Proteins Using Machine Learning Methods

open access: yesMolecules, 2023
Antimicrobial resistance (AMR) is a major problem and an immediate alternative to antibiotics is the need of the hour. Research on the possible alternative products to tackle bacterial infections is ongoing worldwide.

Reconstitution of Holin Activity with a Synthetic Peptide Containing the 1–32 Sequence Region of EJh, the EJ-1 Phage Holin [PDF]

open access: yesJournal of Biological Chemistry, 2003
Pneumococcal EJ-1 phage holin (EJh) is a hydrophobic polypeptide of 85 amino acid residues displaying lethal inner membrane disruption activity. To get an insight into holin structure and function, several peptides representing the different topological regions predicted by sequence analysis have been synthesized.

Functional Dissection of P1 Bacteriophage Holin-like Proteins Reveals the Biological Sense of P1 Lytic System Complexity

open access: yes, 2022
P1 is a model temperate myovirus. It infects different Enterobacteriaceae and can develop lytically or form lysogens. Only some P1 adaptation strategies to propagate in different hosts are known.
