David Picton (Durham University, UK) and colleagues published a new paper in Nucleic Acids Research showing the phage defence island of a multidrug resistant plasmid uses both BREX and type IV restriction for complementary protection from viruses. The authors also present the first structure of a GmrSD-family type IV restriction enzyme and acknowledge the work of 97 undergrads in isolating all 30 phages used in the study!
