Functional complementation between bacterial MDR-like export systems: colicin V, alpha-hemolysin, and Erwinia protease.

abstract：:The restriction systems McrA and McrB of Escherichia coli K-12 are known to attack DNA containing modified cytosine. In strains lacking both activities, however, we observed that DNA methylated at CG dinucleotides (as is mammalian DNA) was still significantly restricted. We show that this substantial barrier to the ac...
