Transformation of Bacillus subtilis by single-stranded plasmid DNA.
The single-stranded form of a pE194-based plasmid transformed Bacillus subtilis protoplasts at least as efficiently as did the double-stranded plasmid, but the single-stranded form did not detectably transform B. subtilis competent cells.
متن کاملIntroduction of a Streptococcus cremoris plasmid in Bacillus subtilis.
Streptococcus cremoris Wg2 plasmid pWV01 was introduced in Bacillus subtilis by protoplast transformation. The yield of pWV01 isolated from B. subtilis was low. pWV01 contains a unique site for the restriction endonuclease MboI.
متن کاملPlasmid deletion formation in Bacillus subtilis.
Plasmid pGP1 carrying a penP-lacZ fusion was used to study structural plasmid instability in Bacillus subtilis. In only one of 28 sequenced deletion junction points in the penP-lacZ region short direct repeats (10 bp) and flanking imperfect inverted repeats (12 bp) were associated with endpoints. In 27 deletions no repeated sequences of more than 3 bp were present at the endpoints. In 15 of the...
متن کاملEffect of protein synthesis on plasmid maintenance in Streptococcus faecalis.
Plasmid-to-chromosome ratios in Enterobacteriaceae, upon interruption of protein synthesis by chloramphenicol, are either conserved or increased when measured by dye buoyant density centrifugation. We have found, on the other hand, that the effect of inhibition of protein synthesis on the amount of covalently closed circular deoxyribonucleic acid visualized by this method in two strains of Stre...
متن کاملPlasmid deoxyribonucleic acid in Bacillus subtilis and Bacillus pumilus.
Two of eighteen strains of Bacillus subtilis examined contained covalently closed circular duplex deoxyribonucleic acid (DNA) of homogeneous size and buoyant density. Strain ATCC 15841 contained about 16 copies per chromosome of plasmid pPL1, a circular DNA element having a molecular weight of about 4.7 times 10(6) and a buoyant density of 1.700. Strain ATCC 7003 contained about one to two copi...
