Several common protein structural motifs are now known to be involved in DNA recognition and binding. What are these, and how would researchers use genomic data to help figure out if new candidate genes encode such DNA-binding proteins?
What will be an ideal response?
DNA-binding structural motifs of proteins include zinc and leucine zippers and the helix-turn-helix (HTH) motif. Researchers can electronically scan the sequence of new genes for the particular nucleotide sequence underlying such motifs, thereby identifying them as candidate DNA recognition or binding proteins.
