The concerted action of DNA gyrase and RecA protein of Escherichia coli on intact and gapped homologous or partially homologous plasmid DNA molecules leads to the formation of covalently closed DNA containing one strand of each parental molecule. Large regions of non-homology can be incorporated into the closed circular duplex. Both proteins are essential for the reaction to take place, and type I topoisomerase cannot substitute for DNA gyrase.
