A novel bacteriophage defence mechanism: the anti-restriction protein

N Spoerel et al. Nature. 1979.

Abstract

Bacteriophage T3 and T7 protect their DNA from restriction by producing, as the earliest detectable phage functions, anti-restriction proteins. Although the two phage proteins differ in their chromatographic and antigenic properties, they act by the same mechanism: the anti-restriction proteins inhibit E. coli K12 restriction endonuclease by direct interaction.
