Fig. 13From: An affinity-structure database of helix-turn-helix: DNA complexes with a universal coordinate systemStructural alignment of HTH-DNA complexes. Two views (different viewing angles) of the 63 structurally aligned HTH-DNA complexes in the final database. The Cα traces of recognition α-helices are shown in blue and the C3’ traces of DNA helices are shown in pinkBack to article page
