fimE

fimE gene

CUHK-HongKong-SBS 2024

In Escherichia coli, FimB, together with FimE, acts as a recombinase that catalyzes the site-specific recombination essential for the inversion of a 314-bp invertible DNA element called the fim switch (fimS). This mechanism is crucial for controlling the transcription of the type I fimbrial structural genes, fimA, in a process known as phase-variation switching (1). The fimS element contains the promoter that drives the expression of these structural genes, whereas FimE is responsible for deactivating fimA (2).
