Figure 6From: Frequent occurrence of recognition Site-like sequences in the restriction endonucleasesAmino acids in REs coded by RS-like codons and co-located with RSs. The solid spirals indicate the dsDNA; the red/pink and blue/light blue lines are the RSs while the white lines are not RSs. (EcoRI is an exception, there is only a single DNA strand), a.a.: amino acid. The ribbons belonging to the amino acids are green.Back to article page
