Interplay between the temperate phages PY54 and N15, linear plasmid prophages with covalently closed ends.
The objective of this study was to determine whether the temperate Yersinia enterocolitica phage PY54 may interact with the related Escherichia coli phage N15 during both the lysogenic and the lytic cycle in the same cell. The PY54 and N15 prophages are linear plasmids which have been shown to be compatible and stably replicating in E. coli and Yersinia. In E. coli, the PY54 prophage does not r...
متن کاملThe linear plasmid prophage Vp58.5 of Vibrio parahaemolyticus is closely related to the integrating phage VHML and constitutes a new incompatibility group of telomere phages.
Vibrio parahaemolyticus O3:K6 pandemic strains recovered in Chile frequently possess a 42-kb plasmid which is the prophage of a myovirus. We studied the prototype phage VP58.5 and show that it does not integrate into the host cell chromosome but replicates as a linear plasmid (Vp58.5) with covalently closed ends (telomeres). The Vp58.5 replicon coexists with other plasmid prophages (N15, PY54, ...
متن کاملThe pKO2 linear plasmid prophage of Klebsiella oxytoca.
Temperate bacteriophages with plasmid prophages are uncommon in nature, and of these only phages N15 and PY54 are known to have a linear plasmid prophage with closed hairpin telomeres. We report here the complete nucleotide sequence of the 51,601-bp Klebsiella oxytoca linear plasmid pKO2, and we demonstrate experimentally that it is also a prophage. We call this bacteriophage phiKO2. An analysi...
متن کاملIndependence of bacteriophage N15 lytic and linear plasmid replication from the heat shock proteins DnaJ, DnaK, and GrpE.
The chromosome of the temperate bacteriophage N15 replicates as a linear plasmid with covalently closed ends (or hairpins) when it forms a lysogen. I found that, in contrast to the cases for lambda and the low-copy-number plasmids F and P1, both phage and plasmid replication of N15 are independent of the heat shock proteins DnaJ, DnaK, and GrpE.
متن کاملThe repA gene of the linear Yersinia enterocolitica prophage PY54 functions as a circular minimal replicon in Escherichia coli.
The Yersinia enterocolitica prophage PY54 replicates as a linear DNA molecule with covalently closed ends. For replication of a circular PY54 minimal replicon that has been derived from a linear minireplicon, two phage-encoded loci are essential in Escherichia coli: (i) the reading frame of the replication initiation gene repA and (ii) its 212-bp origin located within the 3' portion of repA. Th...
