Vol 43(2009) N 3 p. 480-484; A.B. Gordeev, A.V. Efimov Novel structural tree of (α + β)-proteins containing ABCD units Institute of Protein Research, Russian Academy of Sciences, Pushchino, Moscow Region, 142290, RussiaReceived - 2008-07-15; Accepted - 2008-09-30 A database of 926 (α + β)-proteins and (α + β)-domains containing ABCD units, including 401 non-homologous, was compiled from the Protein Data Bank (total of 2636 PDB entries). A novel structural tree of this structural class of proteins was constructed to include 286 possible polypeptide chain folds. A structural classification of (α + β)-proteins containing ABCD unit was developed on the basis of the structural tree. The database and the structural tree are available at http://strees.protres.ru/. Modeling, classification, database, protein folding, structural motif, structural similarity |
