Improving prediction of secondary structure, local backbone angles, and solvent accessible surface area of proteins by iterative deep learning.

TL;DR: The accuracy of the iterative use of predicted secondary structure and backbone torsion angles and dihedrals based on Cα atoms is higher than those of model structures from current state-of-the-art techniques, suggesting the potentially beneficial use of these predicted properties for model assessment and ranking.
Journal ArticleDOI

Capturing non-local interactions by long short-term memory bidirectional recurrent neural networks for improving prediction of protein secondary structure, backbone angles, contact numbers and solvent accessibility.

TL;DR: The application of LSTM‐BRNN to the prediction of protein structural properties makes the most significant improvement for residues with the most long‐range contacts over a previous window‐based, deep‐learning method SPIDER2.
Journal ArticleDOI

Gram-positive and Gram-negative protein subcellular localization by incorporating evolutionary-based descriptors into Chou׳s general PseAAC

TL;DR: This study proposes two segmentation based feature extraction methods and shows that by applying a Support Vector Machine (SVM) classifier to the extracted features, they are able to enhance Gram-positive and Gram-negative subcellular localization prediction accuracies by up to 6.4% better than previous studies including the studies that used GO for feature extraction.
Journal ArticleDOI

Sixty-five years of the long march in protein secondary structure prediction: the final stretch?

TL;DR: The time has come to finish off the final stretch of the long march towards protein secondary structure prediction as more powerful deep learning methods with improved capability of capturing long-range interactions begin to emerge as the next generation of techniques forsecondary structure prediction.
Book ChapterDOI

SPIDER2: A Package to Predict Secondary Structure, Accessible Surface Area, and Main-Chain Torsional Angles by Deep Neural Networks

TL;DR: A newly developed method SPIDER2 is described that utilizes three iterations of deep learning neural networks to improve the prediction accuracy of several structural properties simultaneously and provides state-of-the-art, all-in-one accurate prediction of local structure and solvent accessible surface area.
