چکیده
Sequence-based protein tertiary structure prediction is of fundamental importance because the function a ultimately depends on its 3D structure. An accurate residue-residue contact map one essential elements for current ab initio protocols prediction. Recently, with combination deep learning and direct coupling techniques, performance residue has achieved significant progress. However, considerable number Deep-Learning (DL)-based methods are usually time-consuming, mainly they rely different categories data types third-party programs. In this research, we transformed complex biological problem into pure computational through statistics artificial intelligence. We have accordingly proposed feature extraction method to obtain various statistical information from only multi-sequence alignment, followed by training DL model based massive information. The robust in terms test sets, showed high reliability confidence score, could efficiency achieve comparable precisions that relying multi-source inputs.

Contact-based sequence alignment.
This paper introduces the novel method of contact-based protein sequence alignment, where structural information in the form of contact mutation probabilities is incorporated into an alignment routine using contact-mutation matrices (CAO: Contact Accepted mutatiOn). The contact-based alignment routine optimizes the score of matched contacts, which involves four (two per contact) instead of two ...
متن کاملCAB-Align: A Flexible Protein Structure Alignment Method Based on the Residue-Residue Contact Area
Proteins are flexible, and this flexibility has an essential functional role. Flexibility can be observed in loop regions, rearrangements between secondary structure elements, and conformational changes between entire domains. However, most protein structure alignment methods treat protein structures as rigid bodies. Thus, these methods fail to identify the equivalences of residue pairs in regi...
متن کاملResidue-Residue Contact Prediction Based on Evolutionary Computation
In this study, a novel residue-residue contacts prediction approach based on evolutionary computation is presented. The prediction is based on four amino acids properties. In particular, we consider the hydrophobicity, the polarity, the charge and residues size. The prediction model consists of a set of rules that identifies contacts between amino acids.

متن کاملDeep architectures for protein contact map prediction
MOTIVATION Residue-residue contact prediction is important for protein structure prediction and other applications. However, the accuracy of current contact predictors often barely exceeds 20% on long-range contacts, falling short of the level required for ab initio structure prediction. RESULTS Here, we develop a novel machine learning approach for contact map prediction using three steps of...
