Structure Similarity. Another problem in structure alignment is to assess the statistical significance of the similarity between two protein structures. Structure Alignment with MultiSeq Very often comparing structures of different proteins reveal many important information. This set of equivalences is then typically used to superpose the three-dimensional coordinates for each input structure. We compared the resulting alignments in terms of two properties: (i) the number of indels (insertions and deletions) in the resulting sequence alignment and (ii) the structural alignment implied by the secondary structure alignment. Specifically, a 17 µm 1 µm optical cutoff with a normal band structure superlattice requires that the well thickness be controlled to 1.
