From: Genomes of the T4-related bacteriophages as windows on microbial genome evolution
Phage or genome type | Phage | Genome size (bp) | Database reference(1) | ORFs (T4-like/Total) | tRNA genes | Shared or unique properties of the genomes(2) |
---|---|---|---|---|---|---|
T-even | E. coli phage T4 | 168,903 | NC_000866 | 278 | 8 | The T-even type genomes share 85-95% ORF homology with one another and >90% nucleotide sequence identity between most of their shared alleles. Also, these genomes encode glucosyl transferases and dCMP hydroxymethylases, but their DNA modification patterns vary (see text and Table 3). Some members of this cluster are known to be partially compatible with each other in genetic crosses (see text). Phage RB70 (Table 1) might be identical to phage RB51. |
