Fig. 1From: Identification of DNA-binding proteins using multi-features fusion and binary firefly optimization algorithmAn example that illustrates the preferences of certain secondary structure motifs of a protein complex. Panel (a) is a TATA-binding protein (PDB ID: 1AIS_A). The binding surface is composed of strands (red) while the outer region is composed of helices (green). The general secondary structure pattern of this protein is strand-helix-strand-helix-strand-helix-strand-helix. Panel (b) is a transcription initialization protein (PDB ID: 1AIS_B) that is mainly composed of helices (green) and turns (blue)Back to article page
