Secondary structure and rigidity in model proteins
Soft Matter, 2013There is tremendous interest in understanding the role that secondary structure plays in the rigidity and dynamics of proteins. In this work we analyze nanomechanical properties of proteins chosen to represent different secondary structures: α-helices (myoglobin and bovine serum albumin), β-barrels (green fluorescent protein), and α + β + loop ...

A model of morphogenesis for protein secondary structures
Journal of Theoretical Biology, 1991This paper proposes a model for the expected probability distribution for a certain class of biological structures. In particular, a model is derived for the distribution of lengths of helices, sheets, turns, and coils as a function of the length of the structure divided by the length of the protein it is contained in.

Improving Protein Secondary-Structure Prediction by Predicting Ends of Secondary-Structure Segments
2005 IEEE Symposium on Computational Intelligence in Bioinformatics and Computational Biology, 2005Motivated by known preferences for certain amino acids in positions around a-helices, we developed neural network-based predictors of both N and C a-helix ends, which achieved about 88% accuracy. We applied a similar approach for predicting the ends of three types of secondary structure segments.

Structural analysis of protein Secondary Structure by GHT.
2012Structural biology is a branch of life science concerned with the study of the structure of biological macromolecules like proteins. The structure of a protein gives much more insight in its functions than that of its amino acid sequence. Protein structure comparison is important for understanding the evolutionary relationships among proteins ...

Secondary structure prediction and protein design.
Biochemical Society symposium, 1990For 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.
