Distribution of Modules among the Central Regions of the Genornes of Several Actinophages of Faenia and Saccharopolyspora

The central regions of the genomes of 𝜙FR 114, 𝜙FR113 and Mp 1, three temperate phages of the thermophilic actinomycete Faenia, are shown to differ mainly with respect to modules of about 35 kb, designated J-module (𝜙FR114) and N-module (𝜙FR113, Mp1). The distribution of J and N was observed amongst 22 phages of Faenia and Saccharopolyspora; J-module homology was found on six phage genomes, whereas homology to the N-module was detected on ten phage genomes.
