Subunit of: RecFOR complex

Subunit composition of RecFOR complex = [RecF][RecR][RecO]
         ssDNA and dsDNA binding, ATP binding = RecF (summary available)
         recombination and repair = RecR (summary available)
         protein interacts with RecR and possibly RecF proteins = RecO

In Escherichia coli replication is temporarily inhibited after DNA damage, such as caused by UV, but resumes following a period of time commensurate with the removal of the lesions [Chow04]. Replication recovery requires RecA, which has been shown to bind to single-strand DNA, forming filaments which may protect the DNA from nuclease degradation [Courcelle01]. The recF recO and recR gene products have also been shown, in deletion mutation studies, to serve a similar protective function [Courcelle97, Chow04]. In vitro RecF, RecO and RecR have been shown to interact with and stabilize RecA filaments bound to DNA [Courcelle97, Umezu93]. Mutants lacking RecF and RecR also experience a delay in the induction of the SOS response, consistent with their putative role in the stabilization of RecA filaments which are required for SOS induction [Chow04, Whitby95]. In vitro, RecO physically interacts with both RecF and RecR to form RecFO, RecRO or RecFRO complexes [Umezu94].

The early steps of dsDNA break repair by the RecF pathway have been studied in vitro and a model proposed [Handa09].
