Aquaria is a repository for x-ray crystallographic, and nuclear magnetic resonance (NMR) data of large biological molecules and complexes. This resource can be used to find visual representations of a biological molecule of interest. All available structures for a given protein can be viewed at a glance to assist in choosing the most appropriate structure(s) for a given visualization. Once a structure is chosen, users can be directed to the PDB to download coordinate data that can be used with a compatible molecular viewing and manipulation software.

The Uniprot database can be used to find protein sequence and functional information. The information in this database can be combined with 3D structural data to determine the function of the whole protein as well as different domains of the protein. This information can be used to determine, for example, the regions of a membrane protein that are present inside or outside a cell, or the region of a protein that binds to DNA.

The Electron Microscopy Data Bank (EMDB) is a repository for electron microscopy density maps of large biological molecules and complexes. This resource can be used to find visual representations of a biological molecule of interest. A 3D representation of the data can be viewed in the browser, or files containing the coordinate data can be downloaded and used with a compatible molecular viewing and manipulation software.

The PDB Molecule of the Month features select structures from the PDB with introductions by David Goodsell that address structure/function, roles in human health/welfare, and additional resources.

The Protein Data Bank (PDB) is a repository for x-ray crystallographic, and nuclear magnetic resonance (NMR) data of large biological molecules and complexes. This resource can be used to find visual representations of a biological molecule of interest. Various 3D representations of the molecule of interest, including space filling, ball-and-stick, and ribbon models, can be viewed in the browser, or files containing coordinate data can be downloaded to use with compatible molecular viewing and manipulation software (ex. Chimera, mMaya). Other information about the molecule, including sequence length, posttranslational modification locations and common structural motifs, which hint at the functions of different parts of the molecule, can also be found here.

Manually curated, encyclopaedic resource of macromolecular complexes from a number of key model organisms.
