1. A chimeric zinc finger protein that binds to adjacent target sites, the chimeric zinc finger protein comprising:
- (i) a first and a second DNA-binding domain polypeptide of the chimeric zinc finger protein, wherein at least one of the domains comprises an engineered zinc finger polypeptide, and wherein the first domain binds to a first target site and the second domain binds to a second target site, which target sites are adjacent; and
(ii) a flexible linker that is six or more amino acids in length;
wherein the first and second domains are fused with the flexible linker.
