Figure 12From: MICAN : a protein structure alignment algorithm that can handle Multiple-chains, Inverse alignments, C α only models, Alternative alignments, and Non-sequential alignmentsThe definition of the coordinate of CESS. The definition of coordinate of CESS vpara, and vperp for (a) an α helix and (b) a β strand are depicted. In the upper parts, an α helix and a β strand are depicted by a ribbon diagram, as well as by a ball-and-stick C α model. Black balls represents C α atoms of i-th SSSSE that starts from k-th residue. Gray balls represents r i CESS . In the lower parts, v i para and v i perp of the CESS are indicated by dashed arrows colored in blue and red, respectively. (c) An example of schematic representation of a β - α - β motif by a set of CESSs.Back to article page
