Complete Genome Sequences of the Novel Cluster BP Phages Infecting Streptomyces sanglieri, AxeJC, Cumberbatch, Eastland, Eklok, HFrancette, Ignacio, Piccadilly, and Vondra.

The Streptomyces sanglieri bacteriophages AxeJC, Cumberbatch, Eastland, Eklok, HFrancette, Ignacio, Piccadilly, and Vondra form a novel actinobacteriophage cluster, BP. These siphoviruses have circularly permuted genomes with an average size of 37,700 bp and a GC content of 71%. Each genome contains approximately 58 protein-coding genes, with no tRNAs.

Genome Sequences of Streptomyces Phages Amela and Verse.

Amela and Verse are two Streptomyces phages isolated by enrichment on Streptomyces venezuelae (ATCC 10712) from two different soil samples. Amela has a genome length of 49,452, with 75 genes. Verse has a genome length of 49,483, with 75 genes.

A web-based restriction endonuclease tool for mycobacteriophage cluster prediction.

A recent explosion in the amount of genomic data has revealed a large genetic diversity in the bacteriophages that infect Mycobacterium smegmatis. In an effort to assess the novelty of newly described mycobacteriophage isolates and provide a preliminary determination of their probable cluster assignment prior to full genome sequencing, we have developed a systematic approach that relies on restriction endonuclease analysis. We demonstrate that a web-based tool, the Phage Enzyme Tool (or PET), is capable of rapidly facilitating this analysis and exhibits reliability in the putative placement of mycobacteriophages into specific clusters of previously sequenced phages.
