چکیده

We previously developed the first method to predict real valued accessible surface area in proteins, which was shown to contain more information than 100% correct predictions in a binary space of exposure states. Neural networks used for solvent accessibility predictions, however work as good predictors with invisible modeling of knowledge they learn. In view of this a direct statistical analysis of solvent accessibility of residues was desired, in terms of the contribution of residue neighbors in making them buried or exposed to solvent. Present work aims at compiling singlet to quintets of residue fragments and examining, how the solvent accessibility of residues is affected by the change in a neighboring residue in C-terminal, N-terminal or other positions of these residues. In addition, a graphical method of representing solvent accessibility was developed. Online graphical plots for all proteins in the entire Protein Data Bank (PDB) were made available on the web at www.netasa.org/ asa-view/.

A High Performing Tool for Residue Solvent Accessibility Prediction

Many efforts were spent in the last years in bridging the gap between the huge number of sequenced proteins and the relatively few solved structures. Relative Solvent Accessibility (RSA) prediction of residues in protein complexes is a key step towards secondary structure and protein-protein interaction sites prediction. With very different approaches, a number of software tools for RSA predict...

Improving the prediction accuracy of residue solvent accessibility and real-value backbone torsion angles of proteins by guided-learning through a two-layer neural network.

This article attempts to increase the prediction accuracy of residue solvent accessibility and real-value backbone torsion angles of proteins through improved learning. Most methods developed for improving the backpropagation algorithm of artificial neural networks are limited to small neural networks. Here, we introduce a guided-learning method suitable for networks of any size. The method emp...

Predicting Protein Solvent Accessibility with Sequence, Evolutionary Information and Context-based Features

Solvent-accessible surface areas of residues in proteins are key factors in protein folding. Predicting solvent accessibility from protein sequences is significant for modeling the structural and functional characteristics of many proteins. In this work, we introduce an approach of enhancing solvent accessibility prediction accuracy. We derive pseudo-potentials, by considering high-orderinter-r...

Fold recognition by concurrent use of solvent accessibility and residue depth.

Recognizing the structural similarity without significant sequence identity (called fold recognition) is the key for bridging the gap between the number of known protein sequences and the number of structures solved. Previously, we developed a fold-recognition method called SP(3) which combines sequence-derived sequence profiles, secondary-structure profiles and residue-depth dependent, structu...

Analysis and prediction of DNA-binding proteins and their binding residues based on composition, sequence and structural information

MOTIVATION Though vitally important to cell function, the mechanism of protein-DNA binding has not yet been completely understood. We therefore analysed the relationship between DNA binding and protein sequence composition, solvent accessibility and secondary structure. Using non-redundant databases of transcription factors and protein-DNA complexes, neural network models were developed to util...
