Structural and functional analysis of the kid toxin protein from E. coli plasmid R1.
We have now decided the construction of Child toxin protein from E. coli plasmid R1 concerned in steady plasmid inheritance by postsegregational killing of plasmid-less daughter cells. Child varieties a two-component system with its antagonist, Kis antitoxin. Our 1.four A crystal construction of Child reveals a 2-fold symmetric dimer that intently resembles the DNA gyrase-inhibitory toxin protein CcdB from E. coli F plasmid regardless of the...
