Action of Dam Enzyme on <i>E. coli</i> DNA

Caption

This graphic represents the action of the Dam enzyme on E. coli DNA. The blue circles represent methylation "tags" which are added to the GATC sites on the bacteria's DNA. The clustering of the GATC sites, as seen in the top panel, facilitates Dam's "intrasite hopping" which causes the expression of the pili.
