WebMay 10, 2010 · Dali Database is updated twice a year and contains precomputed structural alignments of PDB90 against the full PDB. The query structure is mapped to the closest representative in PDB90 and the structure comparison scores are recomputed using the transitive alignment via the representative. WebThe Dali database is a structural classification based on precomputed all-against-all structural similarities within the PDB. The resulting hierarchical classification can be browsed on the Web and is linked to protein sequence classification resources. All Dali resources use an identical algorithm for structure comparison. argo surya adhi dewantoro
