The RecA protein of Escherichia coli, and all
filament-forming homologues identified to date, promote DNA strand
exchange by a common, ordered pathway. A filament is first formed on
single-stranded DNA, followed by uptake of the duplex substrate.
These proteins are thereby targeted to single-strand gaps and tails
where recombinational DNA repair is required. The observed course of
DNA strand exchange promoted by the RecA protein from the extremely
radioresistant bacterium Deinococcus radiodurans is the
exact inverse of this established pathway. This reaction lies at the
heart of a remarkably efficient system for the repair of DNA damage.
