The NCBI Structure Group

.. maintains MMDB, a database of macromolecular 3D structures, as well as tools for their visualization and comparative analysis. MMDB, the Molecular Modeling Database, contains experimentally determined biopolymer structures obtained from the Protein Data Bank (PDB).

Structure highlights

A new version of the macromolecular structure viewer Cn3D is now available. New features in Cn3D 4.1 include: new and improved alignment algorithms, VAST alignment import, taxonomy viewer, and a native Mac OSX version. More...

Text searches in MMDB (use the search toolbar at the top of this page) will yield Structure Query pages, providing access to entries that matched the keywords. Structure Summary pages for one/several/all of these may be retrieved. From the Structure Summary pages one may:

• access amino acid and nucleic acid sequences
• retrieve PubMed documents
• get taxonomy information
• view sequence neighbors
• view structure neighbors
