Table 2 Composition of the datasets used in this work

From: Avoidance of recognition sites of restriction-modification systems is a widespread but not universal anti-restriction strategy of prokaryotic viruses

Dataset Number of different sites Number of different genomes Number of (site, genome) pairs
Experimental dataset 494a 2861b 66,704
Control dataset 1 899 3407 3,062,893
Control dataset 2 899 4021 3,614,879
  1. aR-M systems encoded in the genomes of the known phage hosts recognize 494 among all 899 known RS. bOnly 2861 phages among 3407 have known host species with available data on the encoded R-M systems
