title: Restriction mapping and close relationship of the DNA of Streptomyces erythraeus phages 121 and SE-5.
abstract: The biological properties and genome structure of two actinophages, 121 and SE-5, infecting Streptomyces erythraeus were characterized. They had the same host range (limited to S. erythraeus) and similar DNA G + C contents (around 60 mol %). Restriction maps of their genomes also showed many similarities. The close relationship between the two phages was confirmed by DNA hybridization experiments: large parts of their genomes were homologous, except for a segment in the middle of the map, where no hybridization was detected.
