ATP-induced conformational changes in the restriction endonuclease from Escherichia coli K-12.
ATP induces a conformational change in the Escherichia coli K-12 restriction enzyme that allows it to discriminate between unmodified and modified DNA recognition sequences. This conformational change does not require ATP hydrolysis. However, ATP hydrolysis is a requirement for DNA cleavage.
