Triage protein fold prediction.

We have constructed, in a completely automated fashion, a new structure template library for threading that represents 358 distinct SCOP folds where each model is mathematically represented as a Hidden Markov model (HMM). Because the large number of models in the library can potentially dilute the prediction measure, a new triage method for fold prediction is employed. In the first step of the ...

Protein fold recognition by prediction-based threading.

In fold recognition by threading one takes the amino acid sequence of a protein and evaluates how well it fits into one of the known three-dimensional (3D) protein structures. The quality of sequence-structure fit is typically evaluated using inter-residue potentials of mean force or other statistical parameters. Here, we present an alternative approach to evaluating sequence-structure fitness....

Some New Features for Protein Fold Prediction

In this paper we propose several sets of new features for protein fold prediction. The first feature set consisting of 47 features uses only the sequence information. We also define four different sets of features based on hydrophobicity of amino acids. Each such set has 400 features which are motivated by folding energy modeling. To define these features we have considered pair-wise amino acid...

Mining of protein contact maps for protein fold prediction

Contact maps have been used in ab initio methods for the problem of protein structure prediction problem. Secondary structures and contacts made by the residues are clearly visible in the contact maps where helices are seen as thick bands and the beta sheets are seen as orthogonal to the diagonal. This paper explores the idea of extracting rules from contact maps to represent “protein fold” inf...

Enhancing Protein Fold Prediction Accuracy Using Evolutionary and Structural Features

Protein fold recognition (PFR) is considered as an important step towards the protein structure prediction problem. It also provides crucial information about the functionality of the proteins. Despite all the efforts that have been made during the past two decades, finding an accurate and fast computational approach to solve PFR still remains a challenging problem for bioinformatics and comput...
