Mathematical and Machine Learning Approaches for Classification of Protein Secondary Structure Elements from Cα Coordinates

Biomolecules, 2023
Determining Secondary Structure Elements (SSEs) for any protein is crucial as an intermediate step for experimental tertiary structure determination. SSEs are identified using popular tools such as DSSP and STRIDE.

Protein secondary structure in spider silk nanofibrils

Nature Communications, 2022
Secondary fibril structure is a key component of the mechanical properties of protein materials like silk, yet, limited information is known about the internal structure of these protein fibrils. Here, the authors report on the use of polarised Raman and

Enhancing fragment-based protein structure prediction by customising fragment cardinality according to local secondary structure

BMC Bioinformatics, 2020
Background Whenever suitable template structures are not available, usage of fragment-based protein structure prediction becomes the only practical alternative as pure ab initio techniques require massive computational resources even for very small ...

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.

Prediction of protein secondary structure based on an improved channel attention and multiscale convolution module

Frontiers in Bioengineering and Biotechnology, 2022
Prediction of the protein secondary structure is a key issue in protein science. Protein secondary structure prediction (PSSP) aims to construct a function that can map the amino acid sequence into the secondary structure so that the protein secondary ...

Pervasive, conserved secondary structure in highly charged protein regions.

PLoS Computational Biology, 2023
Understanding how protein sequences confer function remains a defining challenge in molecular biology. Two approaches have yielded enormous insight yet are often pursued separately: structure-based, where sequence-encoded structures mediate function, and
