Abstract excerpt
The pnd system of plasmid R483 mediates plasmid stabilization by killing of plasmid-free cells. The pnd mRNA is very stable and can be translated into PndA protein, a cell toxin which kills the cells from within by damaging the cell membrane. Translation of the pnd mRNA is inhibited by the PndB antisense, a small labile RNA of 63 nt. The rapid decay of the PndB antidote leads to onset of PndA synthesis in...
