Deep learning takes on protein folding In 1972, Anfinsen won a Nobel prize for demonstrating connection between protein’s amino acid sequence and its three-dimensional structure. Since 1994, scientists have competed in the biannual Critical Assessment of Structure Prediction (CASP) protein-folding challenge. methods took center stage at CASP14, with DeepMind’s Alphafold2 achieving remarkable accuracy. Baek et al . explored network architectures based DeepMind framework. They used three-track...

Understanding the evolution of a protein, including both close and distant relationships, often reveals insight into its structure function. Fast easy access to such up-to-date information facilitates research. We have developed hierarchical evolutionary classification all proteins with experimentally determined spatial structures, presented it as an interactive updatable online database. ECOD (Evolutionary Classification protein Domains) is distinct from other structural classifications in...

ABSTRACT ECOD (Evolutionary Classification Of protein Domains) is a comprehensive and up‐to‐date structure classification database. The majority of new structures released from the PDB (Protein Data Bank) each week already have close homologs in hierarchy thus can be reliably partitioned into domains classified by software without manual intervention. However, those proteins that lack confidently detectable require careful analysis experts. Although many bioinformatics resources rely on...

Rossmann folds are ancient, frequently diverged domains found in many biological reaction pathways where they have adapted for different functions. Consequently, discernment and classification of their homologous relations function can be complicated. We define a minimal Rossmann-like structure motif (RLM) that corresponds the common core known use this to identify all RLM Protein Data Bank (PDB), thus finding constitute about 20% 3D structures.

Abstract Interactions between proteins and small organic compounds play a crucial role in regulating protein functions. These interactions can modulate various aspects of behavior, including enzymatic activity, signaling cascades, structural stability. By binding to specific sites on proteins, induce conformational changes, alter protein–protein interactions, or directly affect catalytic activity. Therefore, many drugs available the market today are molecules (72% all approved last 5 years)....
