Exploring Protein Fold Space

Biomolecules, 2020
The model of protein folding proposed by Ptitsyn and colleagues involves the accretion of secondary structures around a nucleus. As developed by Efimov, this model also provides a useful way to view the relationships among structures.

Sulfur-mediated chalcogen versus hydrogen bonds in proteins: a see-saw effect in the conformational space

QRB Discovery, 2023
Divalent sulfur (S) forms a chalcogen bond (Ch-bond) via its σ-holes and a hydrogen bond (H-bond) via its lone pairs. The relevance of these interactions and their interplay for protein structure and function is unclear.

PS4: a next-generation dataset for protein single-sequence secondary structure prediction

BioTechniques, 2023
Protein secondary structure prediction is a subproblem of protein folding. A light-weight algorithm capable of accurately predicting secondary structure from only the protein residue sequence could provide useful input for tertiary structure prediction ...

Comparative visualization of protein secondary structures [PDF]

BMC Bioinformatics, 2017
Protein function is determined by many factors, namely by its constitution, spatial arrangement, and dynamic behavior. Studying these factors helps the biochemists and biologists to better understand the protein behavior and to design proteins with modified properties.

MAS NMR detection of hydrogen bonds for protein secondary structure characterization [PDF]

, 2020
Hydrogen bonds are essential for protein structure and function, making experimental access to long-range interactions between amide protons and heteroatoms invaluable. Here we show that measuring distance restraints involving backbone hydrogen atoms and

Extended secondary structures in proteins

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2014
Super secondary structures of proteins have been systematically searched and classified, but not enough attention has been devoted to such large edifices beyond the basic identification of secondary structures. The objective of the present study is to show that the association of secondary structures that share some of their backbone residues is a ...
