Here are brief explanations for SCOP, MMDB, and NDB:
- SCOP (Structural Classification of Proteins): SCOP is a database that classifies protein structures based on their evolutionary and structural relationships. It organizes proteins into a hierarchy of classes, folds, superfamilies, and families.
- MMDB (Molecular Modeling Database): MMDB is a database managed by NCBI that contains 3D macromolecular structures, including proteins and nucleic acids. It integrates structural data with functional information and provides tools for visualization and analysis.
- NDB (Nucleic Acid Database): NDB is a database that specializes in the 3D structures of nucleic acids like DNA and RNA. It stores information on their conformations and interactions, supporting research in structural biology and bioinformatics.
