Abstract
Using a variety of genomic (BLASTN, ClustalW) and proteomic (Phage Proteomic Tree, CoreGenes) tools we have tackled the taxonomic status of members of the largest bacteriophage family, the Siphoviridae. In all over 400 phages were examined and we were able to propose 39 new genera, comprising 216 phage species, and add 62 species to two previously defined genera (Phic3unalikevirus; L5likevirus) grouping, in total, 390 fully sequenced phage isolates. Many of the remainders are orphans which the Bacterial and Archaeal Viruses Subcommittee of the International Committee on Taxonomy of Viruses (ICTV) chooses not to ascribe genus status at the time being.

Abstract
The location and structure of the cos ends of bacteriophage D3, which infects Pseudomonas aeruginosa strain PAO, has been determined using a combination of deletion analysis, transposon mutagenesis, and sequencing directly off the phage DNA. Phage D3 was found to have 9-bp 3' cos ends, making it the first phage of a Gram-negative organism known to have 3' cos ends. A 700-bp region flanking the cos site was necessary for efficient transduction of D3 cosmid derivatives. This region was found to contain incomplete inverted repeat sequences flanking the cos site, along with adenine-rich repeats homologous to coliphage gama Ter binding sites. Possible IHF binding sites were also present.

Abstract
The sre gene (ORF469) of the R4 phage encodes a protein similar to the resolvase-DNA invertase family proteins. Insertional gene disruption of sre prevented a lysogen from entering the lytic cycle, implying that Sre protein is a site-specific recombinase needed for excision of the R4 prophage genome (M. Matsuura, T. Noguchi, T. Aida, M. Asayama, H. Takahashi, and M. Shirai, J. Gen. Appl. Microbiol. 41:53-61, 1995). To determine whether this sre gene is also necessary for the integration reaction, we studied its function by integration plasmid analysis. When deletions, frameshifts, and site-directed mutations that caused an amino acid substitution of Ser-17 for Ala were introduced into the sre structural gene, transformation efficiency of Streptomyces parvulus 2297 with these plasmid DNAs was severely reduced. However, an adenine insertion just before the possible initiation codon of the sre gene did not significantly decrease the efficiency. These data suggest that the Sre protein is a site-specific recombinase responsible for integration of the R4 phage genome.

Abstract
The cohesive termini of the DNA genome of the lactococcal bacteriophage c2 were directly sequenced and appeared to be complementary, non-symmetrical, 9-nucleotide single-stranded, 3' extended DNAs, with the following sequence: 5'-GTTAGGCTT-3' 3'-CAATCCGAA-5'. DNA located on either side of the cohesive ends was sequenced and several repeats and a region with the potential for a DNA bend were found. Previously sequenced cos regions of 13 other bacteriophages were also examined for similar sequence features. All of the bacteriophages from gram-positive hosts had 3' extended DNA termini, in contrast to the bacteriophages from gram-negative hosts, which had 5' extended DNA termini. All bacteriophages had a region of dyad symmetry close to the cohesive termini. A 7.3 kb DNA fragment of the c2 genome containing the cos sequences was cloned; transduction experiments demonstrated that these cloned sequences could act as a substrate for packaging enzymes of phage c2.

Abstract
The sequence of the cohesive ends of actinophage RP3 DNA has been determined. As with all other phages of Gram-positive bacteria that have been studied sofar, RP3 DNA has 3'-protruding ends. A shuttle cosmid has been constructed containing this cos area which can be efficiently transduced by phage RP3 to host cells of Streptomyces rimosus.

Abstract
The location, structure and nature of the cos site of the Lactococcus lactis bacteriophage sk1 was determined using a Taq DNA polymerase runoff sequencing technique. The cos site contains a single-stranded 3' overhang of 11 nucleotides. The region surrounding cos contains several features which may be involved in the binding and catalytic action of a phage terminase. These include four putative terminase-binding sites which show some homology to lambda R-sites, an 11-bp direct repeat, a 10-bp inverted repeat, a string of eight consecutive C residues and six copies of the pentanucleotide, AATCT. The spacing between adjacent copies of the pentanucleotides would place them on the same side of the DNA helix.

Abstract
Temperate bacteriophage NJL of Rhodococcus rhodochrous has a 49-kb linear double-stranded DNA with cohesive ends (cos). NJL DNA has unique target sites for HindIII and SspI, two target sites each for NheI and ScaI, and no cleavage site for AxyI, DraI, EcoRI, SacI, and SphI. The single-stranded regions of cos ends were ligated to each other with T4 DNA ligase, removed with mung bean nuclease, or blunted with the Klenow large fragment of DNA polymerase I; then the sequences of the cos ends were determined. Comparison of these sequences revealed that the single-stranded regions are complementary and 18 bases long and protrude at the 3' ends; they have the following sequences: 5'-TTGGCACCGTGGGAGGAG-3' and 3'-AACCGTGGCAC CCTCCTC-5'. A physical map of NJL was constructed by a cos mapping method based on information about the structure of the cohesive ends and multiple digestions with restriction endonucleases.

Abstract
The nucleotide sequence of the DNA regions flanking the cohesive end site of the temperate lactococcal bacteriophage phi LC3 was determined. Four pairs of sequence repeats of 8 to 13 base-pairs in length were revealed close to the cohesive ends. These repeats possibly represent signal sequences involved in phage DNA maturation and packaging. The start of an open reading frame was localized only 42 nucleotides from the left end of the phi LC3 phage double-stranded region, implying that transcription probably proceeds across the cos site. Compilation of the characteristics of the DNA termini of bacteriophages with complementary cohesive DNA ends suggests that phages of Gram-negative bacteria generally carry 5'-protruding single-strands whereas those of Gram-positive hosts carry 3'-protruding ends.

Abstract
The cohesive ends site (cos) of actinophage R4 was delimitated by assaying the in vivo packaging activity of cosmid derivatives in Streptomyces lividans. A region of 66 bp from -30 to +36 from the center of cohesive ends was required for the basal level of packaging activity. Two additional regions outside the basal sequences from -39 to -31 and from +37 to +97 were necessary for the high level of activity, defined as the accessory sequences. Direct- or inverted-repeat sequences were found within the delimitated region, which might be involved in the recognition by the terminase of actinophage R4.
