title: The restriction-modification system in Streptomyces flavopersicus.
abstract: To clone bifunctional vectors in streptomycetes, it was necessary to define the restriction-modification system of Streptomyces flavopersicus. Plasmid DNA from bifunctional vectors pIJ699 and pXED3-13, isolated from E. coli strains with different methylation systems: E. coli DH5 alpha (dam+ dcm+), E. coli MB5386 (dam dcm), E. coli CB51 (dam dcm+), E. coli NM544 (dam+ dcm), was used for transformation of protoplasts from strain S. flavopersicus. Restriction of dcm-methylated DNA from S. flavopersicus was established. As a host in the intermediate cloning strain E. coli NM544 (dam+ dcm) should be used, as the dcm-transmethylase-dependent strain S. flavopersicus does not process DNA from this strain.
