Naturalpeptidedatabase Peptide databases serve as crucial repositories for researchers studying the vast and complex world of peptides. These specialized peptide databases compile extensive information, ranging from sequences and structures to functions and experimental data, enabling scientists to efficiently search, analyze, and characterize peptides. With a growing number of these resources available, understanding their scope and purpose is essential for accelerating research in fields like drug discovery, proteomics, and immunology.作者：PM Martins·2021·被引用次数：65—Thisdatabaseis a comprehensive, general purpose and up-to-date protein–peptideresource that contains over 19,000 high-resolution structures ...
The landscape of peptide databases is diverse, with many focusing on specific types of peptides or research areasPepBank is a database of peptidesbased on sequence text mining and public peptide data sources. Only peptides that are 20 amino acids or shorter are stored.. For example, Antimicrobial Peptide Databases are invaluable for identifying and studying peptides with antibacterial, antifungal, or antiviral properties. Resources like DBAASP and CAMPR4 manually curate data on antimicrobial peptides (AMPs), providing details on their sequences, activities, and target organisms. Similarly, databases dedicated to therapeutic peptides like THPdb offer insights into approved and investigational peptide-based drugs, consolidating vital information for the development of new treatments.2026年1月1日—Host defense animalpeptides(76% of naturalpeptides) · Experiment-determined 3D structures · A powerfuldatabasesearch engine for natural, ...
Beyond specific functional categories, broader peptide databases cater to a wider range of research needs. PeptideAtlas is a prominent example, offering a multi-organism compendium of peptides identified through tandem mass spectrometry experiments, making it a cornerstone for proteomics research. UniProt, while a broader protein database, also contains extensive peptide information and functional annotationsExploring Synthetic Peptide Databases: Your Gateway to .... Other general-purpose databases, such as Peptipedia and PepBank, aim to provide user-friendly platforms for accessing and analyzing diverse peptide sequences and related data.
The utility of peptide databases is significantly amplified when they cater to specialized research interests. For instance, the Immune Epitope Database (IEDB) is a critical resource for immunologists, cataloging experimental data on antibody and T cell epitopes, which are fragments of antigens that trigger an immune response. For those investigating cancer, specialized cancer antigenic peptide databases compile relevant human tumor antigens, aiding in the identification of potential therapeutic targets.The PeptideDB toolhelps to create peptide databasesby in silico digestion ... The created database stores peptide protein relationships in a SQLite ...
The structural aspects of peptides are also well-represented in dedicated databases. The Cyclic Peptide DataBank (CPDB) consolidates structural information on cyclic peptides, which often possess unique biological activities and stabilities. Similarly, PepBDB focuses on the structural characteristics of biological peptide-mediate complex structures, offering insights into molecular interactionsIn 2001, we have started compiling what we thought were the most relevant human tumor antigens, and created adatabase. Each line corresponds to apeptide, ....

The concept of bioactive peptide databases extends to numerous other areas, providing access to peptides involved in signaling pathways, metabolic regulation, and host defense mechanisms作者：B Xiao·2025·被引用次数：3—These includedatabases dedicated to specific functionssuch as antimicrobial peptides, antiviral peptides, glucose-regulating peptides, or ....
The increasing interest in antimicrobial peptides has led to the development of multiple comprehensive databases like dbAMP and CAMPR4, which integrate sequence data with functional annotations and experimental evidence.Peptide Utility (PU) search server: A new tool for ... These resources are crucial for understanding the mechanisms of action of AMPs and for discovering new peptide-based antimicrobials to combat rising antibiotic resistance.
Beyond static data repositories, several peptide databases and associated tools offer advanced analytical capabilities. PeptideDB, for instance, can assist in creating custom peptide databases through in silico digestion, enabling researchers to predict potential peptides from protein sequences. PepQuery provides a targeted peptide search engine for identifying or validating known and novel peptides within large datasets. Propedia is a database designed for searching and visualizing protein-peptide complexes, offering high-resolution structural informationAntimicrobial Peptide Databases as the Guiding Resource ....
The ongoing development and expansion of these peptide databases underscore their indispensable role in modern biological research. By providing structured, accessible, and often computationally enhanced access to peptide data, these resources empower scientists to make new discoveries, develop novel therapeutics, and deepen our understanding of the fundamental roles peptides play in living organisms. As the field of peptide research continues to evolve, these databases will undoubtedly remain at the forefront, facilitating innovation and driving scientific progress.Cyclic Peptide DataBank (CPDB)
