The temperate actinophage RP3 integrates site-specifically into the chromosome of Streptomyces rimosus R6-554. The phage attachment site attP and the hybrid attachment sites of the integrated prophage--attL and attR--were cloned and sequenced. The 54nt core sequence, common to all RP3 related attachment sites, comprises the 3' terminal end of a putative tRNA(Arg)(AGG) gene. AttB bears the complete tRNA gene which is restored in attL after integration. A 7.5kb HindIII fragment, bearing attP, was used to construct an integrative plasmid to simulate the integration process in vivo and to localize the phage genes necessary for site specific integration. The int and xis genes were sequenced and compared to other recombination genes.
