Figure 3From: Complementation between inactive fragments of SssI DNA methyltransferaseFunctional complementation between inactive fragments of M.SssI. Hin6I digestion of plasmids expressing the M.SssI fragments shown above the lanes. Protection against Hin6I digestion is a sign of C5-methylation at CG sites. Plasmids indicated by underlining were prepared from cells grown in the presence of 0.5 % arabinose. M, DNA size marker (Fermentas). Undigested and digested samples are identified by – and + signs, respectively below the lanes.Back to article page
