Bacteriophage P2, scientific name Peduovirus P2 (formerly Escherichia virus P2), [1] is a temperate phage that infects E. coli. It is a tailed virus with a contractile sheath and is thus classified in the genus Peduovirus (formerly P2likevirus), family …

Here, we developed a bacteriophage P4 cosmid system for the delivery of a Cas9 antimicrobial into clinically relevant human gut pathogens Shigella flexneri and Escherichia coli O157:H7. Our P4 cosmid design produces a high titer of cosmid-transducing units without contamination by a …

In this report we examine the prophages present in the available Enterobacteriaceae bacterial genome sequences, with a focus on two very well-studied temperate tailed phage groups, the P2-like and P22-like phages, and on one of the best studied host genera, Salmonella, to determine how they affect our view of the diversity and evolution of taile...

In this study, we used label-free quantitative proteomics to reveal the proteotypes of Lactococcus lactis MG1363 during infection by the virulent phage p2, a model for studying the biology of phages infecting Gram-positive bacteria.

Bacteriophage P2 belongs to a group of bacteriophages found in E. coli and other hosts referred to as the P2-like bacteriophages, that also includes phage 186 [29] and Salmonella phage SopEϕ [30]. These phages share a common genomic organization and all encode a gpO-like protein [10].

Aug 13, 2018 · Phage tails are molecular machines that specifically recognize bacterial host cells, penetrate the cell envelope and deliver the phage genome into the cytoplasm. All tailed phages have a DNA...

Mar 16, 2016 · P2 is the original member of a highly successful family of temperate phages that are frequently found in the genomes of gram-negative bacteria. This article focuses on the organization of the P2 genome and reviews current knowledge about the …

Bacteriophage P4 is dependent on structural proteins supplied by a helper phage, P2, to assemble infectious virions. Bacteriophage P2 normally forms an icosahedral capsid with T =7 symmetry from the gpN capsid protein, the gpO scaffolding protein and the gpQ portal protein.

Feb 17, 2023 · Here, we developed a bacteriophage P4 cosmid system for the delivery of a Cas9 antimicrobial into clinically relevant human gut pathogens Shigella flexneri and Escherichia coli O157:H7. Our P4 cosmid design produces a high titer of cosmid-transducing units without contamination by a helper phage.

P2 is the original member of a highly successful family of temperate phages that are frequently found in the genomes of gram-negative bacteria. This article focuses on the organization of the P2 genome and reviews current knowledge about the function of each open reading frame.
