Polymorphism of Bacterial Restriction-Modification Systems: The Advantage of Diversity

Evolution, 1994
Bacterial restriction-modification systems provide defense against foreign DNA by using a self versus nonself recognition mechanism. A great diversity of recognition motifs is maintained in natural populations. Circumstantial evidence suggests that defense against bacteriophage viruses favors this diversity.

On the Origins, Structures and Functions of Restriction-Modification Enzymes

1993
Typically, restriction-modification (RM) systems consist of two enzymes: an endonuclease that recognizes and cleaves a specific DNA sequence, and a methyltransferase that modifies the same sequence to protect the host chromosome from cleavage. These enzymes also play an important role in genetic engineering and provide insight into the basis of ...

Evolution of restriction-modification systems

2018
Restriction Modification (R-M) systems prevent the invasion of foreign genetic material into bacterial cells and are therefore important in maintaining the integrity of the host genome. The spread of antibiotic resistance, which is proposed to occur via the transfer of foreign genes to the bacterial genome, makes the subject of R-M systems extremely ...
