CASP (critical assessment of structure prediction) assesses the state of the art in modeling protein structure from amino acid sequence. The most recent experiment (CASP13 held in 2018) saw dramatic progress in
We developed and tested the I-TASSER protein structure prediction algorithm in the CASP7 experiment, where targets are first threaded through the PDB library and continuous fragments in the threading alignments are exploited to assemble the global structure. The final models are obtained from the prog...
These include helix hairpins and helical bundles, commonly found in class II bacteriocins such as the well-known food preservative nisin. AMPs with αβ structure often have disulfide bonds, such as those seen in plant defensins' cysteine-stabilized αβ (CSαβ) motif. All-β AMPs have ...
9 To ensure that all forces responsible for the experimentally observed structure are considered, minimizations are done in crystal space, using complete unit cells.2 As a result, one obtains a force field that has stable energy minima as close as possible to native structures. And as shown ...

method — Dense Homolog Retriever (DHR) — detects remote homologs using dense retrieval and protein language models. Its alignment-free nature makes it much faster than traditional approaches, and the newly found remote homologs benefit our understanding of protein evolution, structure and function. ...
Five decades after the first determination of an X-ray protein structure [4], the discovery that up to 30% of the human proteome is disordered in its functional state has completely revolutionized the structure–function dogma [5]. This finding originally led to the view that disordered protein...
SSEmb: A joint embedding of protein sequence and structure enables robust variant effect predictions Article Open access 07 November 2024 Introduction Machine Learning (ML) has become the Swiss army knife for solving many Bioinformatics problems and it has led to many successes in recent years. In...
Genome sequencing projects continue to produce amino acid sequences; however, understanding the biological roles played by these putative proteins requires knowledge of their structure and function [1]. Despite that empirical structure determination methods have provided structural information for some protein...
Protein Structure and Function • Proteins carry out many of the cellular functions. Structural proteins provide structure, enzymes catalyze chemical reactions, regulatory proteins regulate other molecules, and transport proteins move other molecules in and out of the cell. The resulting polypeptide from...
