Protein structure databases (PDB and MMDB) and protein structure classification databases (SCOP and CATH) are described. Protein folding problems are considered. The Web servers for the folding/pattern recognition of proteins such as 3D_PSSM, PredictProtein and FUGUE are presented. Approaches to ...
20世纪60年代后期,Anfinsen首先发现去折叠蛋白或者说变性(denatured)蛋白质在允许重新折叠的实验条件下可以重新折叠到原来的结构,这种天然结构(native structure)对于蛋白质行使生物功能具有重要作用,大多数蛋白质只有在折叠成其天然结构的时候才能具有完全的生物活性。自从Anfinsen提出蛋白质折叠的信息隐含在蛋白质的一级结构...
are applied to convert the primary sequences of protein into numerical feature vectors. As known to all, pseudo amino acid composition is an improved expression on the basis of amino acid composition, not only considering the frequency of amino acid residues in the sequence but ...
Protein-ligand docking is an established tool in drug discovery and development to narrow down potential therapeutics for experimental testing. However, a high-quality protein structure is required and often the protein is treated as fully or partially r
Recent breakthroughs in highly accurate protein structure prediction using deep neural networks have made considerable progress in solving the structure prediction component of the ‘protein folding problem’. However, predicting detailed mechanisms of how proteins fold into specific native structures remains ...

AlphaFold can predict the structures of monomeric and multimeric proteins with high accuracy but has a limit on the number of chains and residues it can fold. Here we show that a combination of AlphaFold and all-atom symmetric docking simulations enables
