The Database of Macromolecular Movements (MolMovDB) contains a collection of animated protein and RNA structures to assist in the exploration of macromolecular flexibility. Software for structure analysis is also available.
The PDB archive contains information about experimentally-determined structures of proteins, nucleic acids, and complex assemblies. The RCSB PDB also provides a variety of tools and resources. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function.
