title: [Pseudomonas aeruginosa bacteriophages with DNA structure similar to the DNA structure of Mu1 phage. II. Evidence for similarity between D3112, B3, and B39 bacteriophages: analysis of DNA splits by restriction endonucleases, isolation of D3112 and B3 recombinant phages].
abstract: It is found that bacteriophages B3 and B39 specific for Pseudomonas aeruginosa have the same genome structure as previously described phage D3112. On the right (S) end of their genomes a variable non-phage DNA is located (approximately 0.9-2.5 kilobases for different phages). It is probable that this variable DNa has its origin from different regions of bacterial chromosome. In genome of one of the phages, B3 phage, such variable DNA (not more than 150 base pairs) was found on the left end of DNA molecule. Isolation of a viable B3XD3112 recombinant phage and analysis of its genome with restriction technique and with studies of homo- and heteroduplex molecules had confirmed genetical relationship of B3 and D3112. Some essential non-homology of B3 and D3112 DNAs have been found on the right ends of genomes of the phages.
