The DNA-binding domain of TAL effectors (TALEs) consists of up to 30 tandem repeats of a 33-amino acid to 35-amino acid motif with two variable residues [termed the repeat variable di-residues (RVDs)] that confer single nucleotide specificity to each repeat so that the repeats linearly define the nucleotide sequence of the binding site (Boch et al. 2009; Moscou and Bogdanove 2009).
