1. A protein complex comprising:
- (a) a first fusion protein comprising a DNA-binding domain and at least one catalytically inactive FokI cleavage domain or cleavage half-domain, wherein the cleavage domain or cleavage half-domain comprises a mutation at one or more of amino acid residues 450, 467 and 469; and
(b) a second fusion protein comprising a zinc finger domain and a FokI catalytically active cleavage half domain,wherein the catalytically inactive FokI cleavage half domain forms a heterodimer with the catalytically active FokI cleavage half-domain of the second fusion protein and further wherein the protein complex induces a single-stranded break in a target double-stranded sequence.
