From: Complementation between inactive fragments of SssI DNA methyltransferase
Dependence of complementation efficiency on fragment length and overlap. Hin6I digestion of plasmids expressing the M.SssI fragments shown above the lanes (the first sample on panel A was not digested). Plasmids were purified from cultures grown in the presence of 0.05 % arabinose. Protection against Hin6I digestion is a sign of C5-methylation at CG sites.
