Local Structure Prediction with Local Structure-based Sequence Profiles
MOTIVATION A large body of experimental and theoretical evidence suggests that local structural determinants are frequently encoded in short segments of protein sequence. Although the local structural information, once recognized, is particularly useful in protein structural and functional analyses, it remains a difficult problem to identify embedded local structural codes based solely on seque...

Global properties of the mapping between local amino acid sequence and local structure in proteins.
Local protein structure prediction efforts have consistently failed to exceed approximately 70% accuracy. We characterize the degeneracy of the mapping from local sequence to local structure responsible for this failure by investigating the extent to which similar sequence segments found in different proteins adopt similar three-dimensional structures. Sequence segments 3-15 residues in length ...
متن کاملLocal Emotions, Global Moods, and Film Structure
Until recently there were only scattered essays and one book attempting to apply cognitivist assumptions to film and emotions.l The very question seemed strange: how could cognitivism, with its emphasis on rational processes, hope to explain the irrational world of filmic emotion? Yet in the past few years several landmark books have appeared which pose compelling answers to that question.2 It ...
متن کاملBridging the protein sequence-structure gap by structure predictions.
The problem of accurately predicting protein three-dimensional structure from sequence has yet to be solved. Recently, several new and promising methods that work in one, two, or three dimensions have invigorated the field. Modeling by homology can yield fairly accurate three-dimensional structures for approximately 25% of the currently known protein sequences. Techniques for cooperatively fitt...
