Targeting individual subunits of the FokI restriction endonuclease to specific DNA strands
Published in Nucleic acids research (01-04-2009)“…Many restriction endonucleases are dimers that act symmetrically at palindromic DNA sequences, with each active site cutting one strand. In contrast, FokI acts…”

Differences between Ca²⁺ and Mg²⁺ in DNA binding and release by the SfiI restriction endonuclease: implications for DNA looping
Published in Nucleic acids research (01-09-2009)“…Many enzymes acting on DNA require Mg²⁺ ions not only for catalysis but also to bind DNA. Binding studies often employ Ca²⁺ as a substitute for Mg²⁺, to…”
