まとめ
共有フォールディングモデルの方が精度は高いが遅い一方、古典的なドッキングは安定しているが標的共有阻害剤設計には精度が低い。
科学分野:
- 創薬および構造生物学
- 計算化学およびバイオインフォマティクス
背景:
- 標的共有阻害剤(TCI)は、強化された薬物特性を提供するが、その合理的な設計は困難である。
- 共有タンパク質-リガンド複合体の構造の正確な予測は重要であるが、堅牢なベンチマークが不足している。
- 共有フォールディングアプローチは、生体分子モデリングにおいて有望であるが、共有複合体予測におけるその性能は十分に調査されていない。
主な方法:
- 218の共有複合体のデータセットであるCoFD-Benchを開発した。
- 古典的なドッキングツール(AutoDock-GPU、CovDock、GNINA)と共有フォールディングモデル(AlphaFold3、Chai-1、Boltz-1x)を評価した。
- リガンドRMSD精度、タンパク質-リガンド相互作用回復、新規ペアでの性能、および計算効率を評価した。
結論:
- CoFD-Benchは、共有複合体予測手法のための厳格な評価フレームワークを提供する。
- 共有フォールディングモデルは、TCI設計においてより高い精度を提供するが、スケーラビリティの課題に直面する。
- 本研究の結果は、共有フォールディングベースのTCI設計戦略およびモデル改善の将来の開発を導く。

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Ligand Binding Sites

Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

Protein Organization
9.0K
Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence....

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...
