[Genetic regulation of plasmid transfer in gram-negative bacteria]. 1986

A P Pekhov, and V P Shchipkov

The data are reviewed on the genetic structure and regulation of tra-genes activity controlling the conjugative transfer of F, F-like plasmids as well as the transfer of some other bacterial plasmids. The effect of the systems inhibiting the conjugational transfer (fin-systems) of F and a number of derepressed F-like plasmids has been characterized on the basis of data obtained by the authors or published data. Possible mechanisms for the systems functioning in the regulation of tra-genes activity are discussed as well as the prospects of their further study.

D005144 F Factor A plasmid whose presence in the cell, either extrachromosomal or integrated into the BACTERIAL CHROMOSOME, determines the "sex" of the bacterium, host chromosome mobilization, transfer via conjugation (CONJUGATION, GENETIC) of genetic material, and the formation of SEX PILI.
