Specialized recombination reactions involving DNA inversions have evolved as a
mechanism to generate genetic diversity within a population. They often function to preadapt …

The inversion enzymes of the FimI system of E. coli also belong to the integrase family.
Since the biological function of this genetic switch resembles that promoted by the members …

The Fis protein of E. coli binds to a recombinational enhancer sequence that is required to
stimulate Hin‐mediated DNA inversion. Fis is also required for efficient lambda prophase …

The Fis protein of Escherichia coli and Salmonella typhimurium stimulates several site-
specific DNA recombination reactions, as well as transcription of a number of genes. Fis …

The recombinational enhancer of the Hin inversion system in Salmonella stimulates
recombination in vitro 150-fold in the presence of the Escherichia coli host factor Fis. To gain …

Site-specific recombinases of the integrase family usually require cofactors to impart
directionality in the recombination reactions that they catalyze. The FimB integrase inverts …

The on-and-off expression (phase variation) of type 1 fimbriae, encoded by fimA, in
Escherichia coli is controlled by the inversion of a promoter-containing 314-base-pair DNA …

Reversible site‐specific inversions of DNA segments occur within the genomes of many
bacteria and their phages. These reactions are catalyzed by a dedicated recombinase and …

FIS protein is involved in several different cellular processes stimulating site-specific
recombination in phages Mu and λ as well as transcription of stable RNA operons in E. coli …

In vitro studies have demonstrated that Hin‐catalysed site‐specific DNA inversion occurs
within a tripartite invertasome complex assembled at a branch on a supercoiled DNA …
