title: Isolation and characterization of Streptomyces erythreus plasmids.
abstract: Streptomyces erythreus strains were found to carry several plasmids of molecular weights ranging from about 2 X 10(6) Mr to 40 X 10(6) Mr. Restriction enzyme maps for the streptomycete plasmids pPC7 and pPC8 were constructed for the enzymes Bg/II, EcoRI, XbaI, HindIII, BamHI and SalI. The smaller, pPC8, plasmid appears to be a naturally occurring deletion variant of pPC7. These plasmids belong to the group of conjugative streptomycete plasmids.
