Abstract	Chromosomal duplication faces many blocks to replication fork progression that could destabilize the genome and prove fatal if not overcome. Overcoming such blocks requires interplay between DNA replication, recombination and repair. The RecG protein of Escherichia coli promotes rescue of damaged forks by catalysing their unwinding and conversion to Holliday junctions. Subsequent processing of this structure allows repair or bypass of the fork block, enabling replication to resume without recourse to potentially mutagenic translesion synthesis or recombination. Such direct rescue of stalled forks might help safeguard genome integrity in all organisms.
