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 ...

Nanoplastics can change the secondary structure of proteins

Scientific Reports, 2019
Submillimetre-sized plastic particles (microplastics and nanoplastics) of waste origin in the environment have been repeatedly suggested in recent years to have severe impact on living organisms. While the uptake of these materials has been unequivocally

Functional RNA Structures in the 3′UTR of Tick-Borne, Insect-Specific and No-Known-Vector Flaviviruses

Viruses, 2019
Untranslated regions (UTRs) of flaviviruses contain a large number of RNA structural elements involved in mediating the viral life cycle, including cyclisation, replication, and encapsidation.

An O(n^5) algorithm for MFE prediction of kissing hairpins and 4-chains in nucleic acids [PDF]

, 2008
Efficient methods for prediction of minimum free energy (MFE) nucleic secondary structures are widely used, both to better understand structure and function of biological RNAs and to design novel nano-structures.

Secondary Structure and Mosaic Structure of Crystals [PDF]

Physical Review, 1932
In the following a brief summary is given of some of the essentials of the theory of the secondary structure. This structure is very sensitive to external disturbing effects which frequently cause the transition of crystals from thermally stable into thermally pseudostable configurations for which the term mosaic structure is proposed.

Changes in protein structure at the interface accompanying complex formation

IUCrJ, 2015
Protein interactions are essential in all biological processes. The changes brought about in the structure when a free component forms a complex with another molecule need to be characterized for a proper understanding of molecular recognition as well as

The secondary structure of RNA under tension

, 2002
We study the force-induced unfolding of random disordered RNA or single-stranded DNA polymers. The system undergoes a second order phase transition from a collapsed globular phase at low forces to an extensive necklace phase with a macroscopic end-to-end

Two-Dimensional Infrared Spectroscopy of Antiparallel β-Sheet Secondary Structure [PDF]

, 2004
We investigate the sensitivity of femtosecond Fourier transform two-dimensional infrared spectroscopy to protein secondary structure with a study of antiparallel β-sheets.

Pseudoknots in RNA secondary structures

Proceedings of the fourth annual international conference on Computational molecular biology, 2000
<p>RNA molecules are sequences of nucleotides that serve as more than mere intermediaries between DNA and proteins, e.g. as catalytic molecules. Computational prediction of RNA secondary structure is among the few structure prediction problems that can be solved satisfactorily in polynomial time. Most work has been done to predict structures that

bpRNA: large-scale automated annotation and analysis of RNA secondary structure

bioRxiv, 2018
While RNA secondary structure prediction from sequence data has made remarkable progress, there is a need for improved strategies for annotating the features of RNA secondary structures.
