The C repressor of the P2 bacteriophage
The C-repressor of bacteriophage P2 (P2 C) is a DNAbinding protein that controls the lifecycle of the P2 bacteriophage by directing it toward the lysogenic mode. P2 C is a 99 amino acids protein, which forms stable homodimers but not higher oligomers in the absence of DNA (Ahlgren-Berg et al. 2007). As opposed to the more common situation where dimeric proteins bind palindromic DNA-sequences, P...
متن کاملComplete Genome Sequence of the Pseudomonas fluorescens Bacteriophage UFV-P2
Milk proteolysis caused by Pseudomonas fluorescens is a serious problem in the dairy industries as a result of its ability to grow under refrigeration. The use of phages to control contaminants in food has been considered an alternative to traditional methods; therefore, a thorough understanding of such organisms is vital for their use. In this study, we show the complete genome sequence and an...
متن کاملAn Escherichia coli Gene Required for Bacteriophage P2-K Interference
The gene old of bacteriophage P2 is known to (i) cause interference with phage A growth; (ii) kill recBmutants of Escherichia coli after P2 infection; and (iii) determine increased sensitivity of P2 lysogenic cells to X-ray irradiation. In all of these phenomena, inhibition of protein synthesis occurs. We have isolated bacterial mutants, named pin (P2 interference), able to suppress all of the ...
متن کاملRegulation of bacteriophage P2 late-gene expression: the ogr gene.
The ogr gene product of bacteriophage P2 is a positive regulatory factor required for P2 late-gene transcription. We have determined the nucleotide sequence of the ogr gene, which encodes a basic polypeptide of 72 amino acids. P2 growth is blocked by a host mutation, rpoA109, in the alpha subunit of DNA-dependent RNA polymerase. The ogr52 mutation, which allows P2 to grow in an rpoA109 strain, ...
متن کاملExtent of host deletions associated with bacteriophage P2-mediated eduction.
A series of independent Escherichia coli K eductants has been isolated and tested to determine the extent of their deletions. The deletions cover the P2 prophage in location H, the his operon, a suppressor of the recBC phenotype (sbcB), the gene for gluconate-6-phosphate dehydrogenase (gnd), a locus involved in cell wall synthesis (rfb), and in some cases all or part of genes involved in methyl...
