Unraveling the late stages of recombinational repair: metabolism of DNA junctions in Escherichia coli.


DNA junctions are by-products of recombinational repair, during which a damaged DNA sequence, assisted by RecA filament, invades an intact homologous DNA to form a joint molecule. The junctions are three-strand or four-strand depending on how many single DNA strands participate in joint molecules. In E. coli, at least two independent pathways to remove the… (More)
