[Comparative study of the plasmid DNA recipient capacity of Escherichia coli K-12 mutants for the main membrane proteins and of mutants with enhanced plasmid transformation efficiency].
The study of the plasmid transformation of E. coli K-12, carried out in mutants with the known damages in the main proteins of the outer membrane, made it possible to reveal the essential role of OmpA protein in this process. The damage of lipoprotein led to a considerable increase in the level of plasmid transformation. The mutants with the enhanced efficiency of plasmid transformation, obtained by the authors, were not connected with lesions in the main proteins of the outer membrane: OmpF, OmpC and OmpA.
