Abstract excerpt

Many promiscuous plasmids encode the antirestriction proteins ArdA (alleviation of restriction of DNA) that specifically affect the restriction activity of heterooligomeric type I restriction-modification (R-M) systems in Escherichia coli cells. In addition, a lot of the putative ardA genes encoded by plasmids and bacterial chromosomes are found as a result of sequencing of complete genomic sequences, suggesting...
