A DNA fragment carrying the genes coding forEco O109I endonuclease andEco O109I methylase, which recognize the nucleotide sequence 5′-(A/G)GGNCC(C/T)-3′, was cloned from the chromosomal DNA ofEscherichia coli H709c. TheEco O109I restriction-modification (R-M) system was found to be inserted between theint andpsu genes from satellite bacteriophage P4, which were lysogenized in the chromosome at the P4 phage attachment site of the correspondingleuX gene observed inE. coli K-12 chromosomal DNA. Thesid gene of the prophage was inactivated by insertion of one copy of IS21 . These findings may shed light on the horizontal transfer and stable maintenance of the R-M system.
