Prediction of Protein Secondary Structure from PDB Structure Information Based on Sequence Segments Homology Searching
In this paper, a novel method to predict protein secondary structure (e.g., helix, beta-sheet and coil) is described. Our method predicts the secondary structure for a query sequence using a segment-wise similarity search, which finds the most probable secondary structure based on similarities between a set of sequence segments of a query sequence and our segment databases: the segment sequence...
متن کاملProtein Secondary Structure Prediction Based on Denoeux Belief Neural Network
Predicting the secondary structure of protein is an important step towards obtaining its three dimensional structure and consequently its function. At present, the best predictors are based on machine learning techniques, in particular neural network architectures. We introduce a new architecture called Denoeux belief neural network (DBNN) for the prediction problem. DBNN uses reference pattern...
متن کاملCompactified Horizontal Visibility Graph for the Language Network
A compactified horizontal visibility graph for the language network is proposed. It was found that the networks constructed in such way are scale free, and have a property that among the nodes with largest degrees there are words that determine not only a text structure communication, but also its informational structure. Construction of networks with text elements, words, phrases or fragments ...
متن کاملProtein secondary structure prediction based on quintuplets
Simple hidden Markov models are proposed for predicting secondary structure of a protein from its amino acid sequence. Since the length of protein conformation segments varies in a narrow range, we ignore the duration effect of length distribution, and focus on inclusion of short range correlations of residues and of conformation states in the models. Conformation-independent and -dependent ami...
متن کاملA characterization of horizontal visibility graphs and combinatorics on words
An Horizontal Visibility Graph (for short, HVG) is defined in association with an ordered set of non-negative reals. HVGs realize a methodology in the analysis of time series, their degree distribution being a good discriminator between randomness and chaos [B. Luque, et al., Phys. Rev. E 80 (2009), 046103]. We prove that a graph is an HVG if and only if outerplanar and has a Hamilton path. The...
