Host specificity of DNA produced by Escherichia coli, X. In vitro restriction of phage FD replicative form.Proc. Nat. Acad. Sci. (USA), 59, 1300-1306, 1968.Order of authorship in the original publication: Linn, Arber. Arber announced the discovery, with proof, of the first restriction endonuclease (restriction enzyme or restrictase)."These enzymes are found in bacteria and archaea and provide a defence mechanism against invading viruses.[4][5] Inside a prokaryote, the restriction enzymes selectively cut up foreign DNA in a process called restriction digestion; meanwhile, host DNA is protected by a modification enzyme (a methyltransferase) that modifies the prokaryotic DNA and blocks cleavage. Together, these two processes form the restriction modification system.[6]" Digital facsimile from PubMedCentral at this link. (Thanks to Juan Weiss for this reference and its interpretation.)
