The two tryptophan residues involved in DNA binding are Trp40 and Trp54, which was
determined by mutagenesis. One more binding site was determined by site-specific mutagenesis.
When His55 is substituted with Leu it decreases binding affinity. All of these residues
are found in a hydrophobic region, which is suitable for nucleotide base interactions.
