title: [Isolation of a plasmid from actinomycin C-producing Streptomyces chrysomallus and its characteristics].
abstract: Until now the identification of plasmids in streptomyces, the producers of actinomycins, has not been reported, although there exist the genetic data on the possible plasmid participation in biosynthesis of these antibiotics. In this paper the data are presented on plasmid identification in two variants of Streptomyces chrysomallus. Plasmids are shown to be identical in both variants differing in productiveness. The restriction map is constructed for this 7000 b. p. plasmid. Plasmid participation in actinomycin biosynthesis and its possible use for molecular cloning in streptomyces are discussed.
