Evaluation of secondary structure predictions in proteins
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1977Data of 33 proteins are used to compare four methods which predict secondary structure from the amino acid sequence. The prediction of alpha-helices according to the histogram method of Argos et al. (Argos, P., Schwarz, J. and Schwarz, J. (1976) Biochim. Biophys.

Protein secondary structure prediction (PSSP) is an important research field in bioinformatics. The representation of protein sequence features could be treated as a matrix, which includes the amino-acid residue (time-step) dimension and the feature ...

Improving protein secondary structure predictions by prediction fusion
Information Fusion, 2009Protein secondary structure prediction is still a challenging problem at today. Even if a number of prediction methods have been presented in the literature, the various prediction tools that are available on-line produce results whose quality is not always fully satisfactory.

Prediction of protein secondary structure at 80% accuracy
Proteins: Structure, Function, and Genetics, 2000Secondary structure prediction involving up to 800 neural network predictions has been developed, by use of novel methods such as output expansion and a unique balloting procedure. An overall performance of 77.2%-80.2% (77.9%-80.6% mean per-chain) for three-state (helix, strand, coil) prediction was obtained when evaluated on a commonly used set of 126

HMM in predicting protein secondary structure
Wuhan University Journal of Natural Sciences, 2003We introduced a new method—duration Hidden Markov Model (dHMM) to predicate the secondary structure of Protein. In our study, we divide the basic second structure of protein into three parts: H (α-Helix), E (β-sheet) and O (others, include coil and turn). HMM is a kind of probabilistic model which more thinking of the interaction between adjacent amino

Study and Prediction of Secondary Structure for Membrane Proteins
Journal of Biomolecular Structure and Dynamics, 2007In this paper we present a novel approach to membrane protein secondary structure prediction based on the statistical stepwise discriminant analysis method. A new aspect of our approach is the possibility to derive physical-chemical properties that may affect the formation of membrane protein secondary structure.

Protein secondary structure prediction with dihedral angles
Proteins: Structure, Function, and Bioinformatics, 2005AbstractWe present DESTRUCT, a new method of protein secondary structure prediction, which achieves a three‐state accuracy (Q3) of 79.4% in a cross‐validated trial on a nonredundant set of 513 proteins. An iterative set of cascade–correlation neural networks is used to predict both secondary structure and ψ dihedral angles, with predicted values ...

The GOR Method for Predicting Secondary Structures in Proteins
1989The widely used term “secondary structure” implies that it is of value to consider the structure of a protein as organized hierarchically. “Hierarchic” relates to the idea that the structure can be considered on at least two levels; there are, in fact, three levels of interest here, namely, the covalent structure (primary), the structural organization ...
