Abstract

The DNA methyltransferase (Mtase) genes of temperate phages SPR, ø3T, SP and 11 can be transferred by transfection and recombination to the genome of the related nonmodifying phage Z. Integration of the Mtase genes occurs in phage Z DNA at a unique location which is homologous with the flanking regions of the Mtase genes of the related phages. In lysogenic cells carrying recombinant phages, expression of the Mtase genes is repressed, irrespective of whether the Mtase genes were derived from phage donors which were homo- or heteroimmune to phage Z.
