Webb1 nov. 2011 · Fig. 3. Late steps of DSB repair in Bacillus subtilis. (a) Repair of one-ended DSBs. RecA-mediated strand invasion leads to the formation of a D-loop intermediate. The invading strand primes DNA synthesis using the intact homologous chromosome as a template to restore the lost genetic information. The replisome assembly machinery … WebbThe RecG of Escherichia coli is needed for normal levels of recombination and for repair of damaged DNA. RecG homologues are found in most bacterial species [4] . Strains carrying mutations in this gene show reduced recombination in conjugational crosses and increased sensitivity to UV, mitomycin C and ionizing radiation [5] , [6] , [7] .

WebbrecG lead to a phenotype with more severe growth defects, implying that RecG participates in the reacti-vation of damaged replication forks [37]. Furthermore, damage inducible stable DNA replication (SDR) is significantly increased in recG mutant strains, suggest-ing that RecG suppresses SDR [38].

WebbDSBR. We propose that RecG prevents a previously unrecognised mechanism of DNA amplification that we call reverse-restart, which generates DNA dou-ble-strand ends from incorrect loading of the replicative helicase at D-loops formed by recombination, and at arrested replication forks.
