Basing on the data obtained by the method of necessary stereochemical requirements of the DNA-recognizing structure helix-turn-helix existence and the available data from literature a conclusion is made that 1) GCN4 protein, probably, recognizes DNA using DNA-recognizing structure helix-turn-helix, localized in the amino acid sequence segment 256–278 and 2) DNA-recognizing structure of GCN4 protein is similar to those of MATα1 and MATα2 proteins, and homoeodomain-containing proteins.
