On the regulation and diversity of restriction in Escherichia coli.
The effect of UV irradiation on restriction mediated by four endogenous restriction systems of E. coli K-12 was investigated using a uniform testing method. Restriction by all four systems was reduced when treated cells were separately challenged with lambda phage carrying modification patterns that elicit restriction by each system. The response of each system was genetically and physiologically distinct.
