1. An isolated, non-naturally occurring DNA-binding polypeptide comprising:
- two or more TALE-repeat units, the TALE repeat units comprising a repeat variable di-residue (RVD) wherein the RVD binds to a nucleotide in a target DNA sequence;
an N-cap polypeptide flanking the N-terminal portion of the TALE-repeat units, wherein the N-cap polypeptide comprises a fragment of a full length N-terminus region of a TALE protein, the fragment comprising residues between N+122 and N+137; and
a C-cap polypeptide flanking the C-terminal portion of the TALE-repeat units, wherein the C-cap polypeptide comprises a fragment of a full length C-terminus region of a TALE protein,wherein the polypeptide binds to DNA.
