Biological Macromolecule Crystallization Database (BMCD) - contains crystal data and the crystallization conditions, which have been compiled from literature. In addition the BMCD contains the NASA Protein Crystal Growth Archive, which includes the crystallization data generated from studies carried out in a microgravity environment supported by NASA.
Crystallography Open Database (COD) - A project accomodating crystal structure atomic coordinates prior to their publication. It is intended to give faster access to the latest structure determinations, openly.
Heavy Atom Databank - collected information on the preparation and characterisation of HEAVY-ATOM derivatives of protein crystals.
Homologous Structure Alignment Database (HOMSTRAD) - is a database of structure-based alignments for homologous protein families. It provides annotated structural alignments in various formats, superimposed structures, links to other databases and the alignment and searching interface to the program FUGUE.
Inorganic Crystal Structure Database (ICSD) - contains complete structural information for inorganic compounds, including compound name, molecular formula, crystal symmetry group, unit cell parameters, atomic coordinates, and temperature factors.
Metalloprotein Database (MDB) - contains quantitative information on all the metal-containing sites available from structures in the PDB distribution.
