The protein secondary structure flexibility

2008
Modeling protein flexibility is a long standing challenge in computational biology with a special impact to protein docking. Relating problems are protein structures alignment and identification of flexible and rigid protein regions, as well as a general definition of a region degree of flexibility.

Comparison of Super-secondary Structures in Proteins

Journal of Molecular Biology, 1973
Abstract A method of comparing the conformations of different, but structurally related proteins is described. Local variations, such as the systematic translation of a helix, or the position of deletions and insertions can be detected, and the correspondence of only marginally similar structures can be measured.

Protein secondary structure

International Journal of Peptide and Protein Research, 1982
A secondary structure prediction technique is proposed which includes nucleation site determination through multiplication of conformational preference parameters as well as weighting factors to represent structurally stabilizing short range interactions.

Modeling secondary structures and secondary structure linkages of protein sequences

2010 IEEE International Conference on Systems, Man and Cybernetics, 2010
In this paper we model protein secondary structures such as a-helices and b sheets and linkages thereof using passive electrical circuit components and obtain the frequency responses of these circuits. An analysis of the frequency responses of these model circuits shows that putative connections can be made between circuit behavior and known ...

Parallelized protein secondary structure prediction

Proceedings of 2004 International Conference on Machine Learning and Cybernetics (IEEE Cat. No.04EX826), 2005
Functional characterization of a protein sequence is one of the most frequent problems in biology. Secondary structure prediction is a useful first step in understanding how the amino acid sequence of a protein determines the native state. There are many previous famous prediction methods available now, although most of them allow users to submit their

Secondary structure prediction and protein design.

Biochemical Society symposium, 1990
For non-homologous proteins, and after cross-validation, the methods reviewed in this article exhibit a probability index (percentage of correctly predicted residues per predicted residues) of 59-65.5% according to the methods employed with a standard deviation of 7% for three conformational states: alpha-helix, beta-strand and coil.

Evaluation of secondary structure predictions in proteins

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1977
Data of 33 proteins are used to compare four methods which predict secondary structure from the amino acid sequence. The prediction of alpha-helices according to the histogram method of Argos et al. (Argos, P., Schwarz, J. and Schwarz, J. (1976) Biochim. Biophys.
