• • Characterizing Metal Binding Sites in Proteins with X-Ray Crystallography

  Characterizing metal binding sites in proteins with X-ray crystallography is a powerful proteomics technique that provides atomic-level details about the roles and mechanisms of metal ions in biomolecules. By analyzing the three-dimensional structures of protein crystals, this method identifies the locations of metal ions and their interactions with surrounding ligands. Such insights are invaluable for understanding the functions of metal ions in catalytic activity, structural stability, and electron ......

• • Top-Down and Bottom-Up Proteomics

  Top-Down and Bottom-Up Proteomics represent two primary strategies in proteomic research, each offering distinct advantages and applications. Top-Down Proteomics involves the analysis of intact proteins using mass spectrometry, preserving the protein's natural state. This approach is particularly valuable for investigating post-translational modifications and protein isoforms. Conversely, Bottom-Up Proteomics entails the enzymatic digestion of proteins into peptides, which are then analyzed by mass sp......

• • Interactome Map

  The interactome map represents a comprehensive and systematic depiction of the interactions among various biomolecules, including proteins, nucleic acids, lipids, and metabolites, within an organism. By graphically representing these complex networks, it serves as a "map" that enables researchers to intuitively understand how biological processes and cellular functions are regulated through these molecular interactions. In recent years, this technology has garnered significant attention and applicatio......

• • Protein Identification and Characterization

  Protein identification and characterization are critical components of proteomics research, aimed at thoroughly analyzing the types, structural features, and functional information of proteins within biological samples. As the final products of gene expression, proteins engage directly in and regulate nearly all biological processes, with a complexity in type and function that far surpasses nucleic acids. The primary tasks in protein identification and characterization involve two main aspects: identi......
