CAPS-DB: a structural classification of helix-capping motifs

J. Segura, B. Oliva, N. Fernandez-Fuentes
2011 Nucleic Acids Research  
CAPS-DB is a database of clusters of structural patterns of different capping types. The clustering algorithm is based in the geometry and the (r-t)space conformation of these regions.  ...  The regions of the polypeptide chain immediately preceding or following an a-helix are known as Ntand Ct cappings, respectively.  ...  As a result a novel and automated structural classification and database of helix cappings, CAPS-DB, is presented.  ...

data (from CAPS-DB)--as the ground truth to train a bidirectional long short-term memory (BiLSTM) model to classify helix cap residues.  ...  Previous work used highly empirical and heuristic methods to manually classify helix capping motifs.  ...  Portions of this work were also supported by UVA and NSF CAREER award MCB-1350957.  ...
