comparative sequence analysis of the dna packaging, head, and tail morphogenesis modules in the temperate cos-site streptococcus thermophilus bacteriophage sfi21.the temperate streptococcus thermophilus bacteriophage sfi21 possesses 15-nucleotide-long cohesive ends with a 3' overhang that reconstitutes a cos-site with twofold hyphenated rotational symmetry. over the dna packaging, head and tail morphogenesis modules, the sfi21 sequence predicts a gene map that is strikingly similar to that of lambdoid coliphages in the absence of any sequence similarity. a nearly one to one gene correlation was found with the phage lambda genes nu1 to h, except for gene ...199910417259
