| the genetic relationship between virulent and temperate streptococcus thermophilus bacteriophages: whole genome comparison of cos-site phages sfi19 and sfi21. | the virulent cos-site streptococcus thermophilus bacteriophage sfi19 has a 37,392-bp-long genome consisting of 44 open reading frames all encoded on the same dna strand. the genome of the temperate cos-site s. thermophilus phage sfi21 is 3.3 kb longer (40,740 bp, 53 orfs). both genomes are very similarly organized and differed mainly by gene deletion and dna rearrangement events in the lysogeny module; gene replacement, duplication, and deletion events in the dna replication module, and numerous ... | 1999 | 10417258 |
