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 FimB protein is a site-specific recombinase that inverts the fimS genetic switch in
Escherichia coli. Based on amino acid sequence analysis alone, FimB has been assigned to …

Phase variable expression of type 1 fimbriae in Escherichia coli arises from a site‐specific
recombination event that inverts a short segment of chromosomal DNA carrying the …

Reversible inversion of the DNA element fimS is responsible for the phase variable
expression of type 1 fimbriae in Escherichia coli. The FimB tyrosine integrase site‐specific …

FimB and FimE are site-specific recombinases, part of the λ integrase family, and invert a
314 bp DNA switch that controls the expression of type 1 fimbriae in Escherichia coli. FimB …

Phase‐variable expression of type 1 fimbriae in Escherichia coli K‐12 involves inversion by
site‐specific recombination of a 314 bp sequence containing the promoter for fim structural …

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 …

Phase‐variable expression of type 1 fimbriae is, in part, controlled by site‐specific DNA
inversion of the fim switch in Escherichia coli. Of the two fim recombinases (FimB and FimE) …

The fim switch is a 314 bp segment of invertible chromosomal DNA that is responsible for
phase‐variable expression of type 1 fimbriae in Escherichia coli. The switch harbours the …

Phase variation of type 1 fimbriae of Escherichia coli requires the site-specific recombination
of a short invertible element. Inversion is catalyzed by FimB (switching in either direction) or …
