Contains crystal data and the crystallization conditions, which have been compiled from literature. Also contains the NASA Protein Crystal Growth Archive, which includes the crystallization data generated from studies carried out in a microgravity environment supported by NASA.

Contains crystal structure information for over 325,000 organic and metal-organic compounds.

A database containing information on Protein Crystallization Conditions. It helps researchers in setting conditions for protein crystallization, thus contributing to reducing the time to analyze protein structures.

A project accomodating crystal structure atomic coordinates prior to their publication. It is intended to give faster access to the latest structure determinations, openly.

The most complete collation of observed molecular and crystallographic symmetry properties to date. A relational database built using Microsoft Access.

Two types of database. One is calculated results for phase diagrams of each ternary system of Fe-Mn-S and Fe-Cr-S systems. Another is a literature database of binary and ternary systems.

Information on the preparation and characterisation of heavy-atom derivatives of protein crystals. Also contains information resulting from an analysis of the binding of these heavy-atoms with proteins in the crystal environment.

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.

Contains records of all inorganic crystal structures, with atomic coordinates, published since 1913.

Contains quantitative information on all the metal-containing sites available from structures in the PDB distribution. Includes search and visualization interfaces.

A database of critically evaluated crystallographic data for metals, including alloys, intermetallics and minerals. Contains chemical, crystallographic and bibliographic data together with associated comments regarding experimental details for each study.

assembles and distributes structural information about nucleic acids.

Aims to provide a fully searchable database for the sequences of peptaibols. It deals primarily with naturally-occurring peptides, generally these have a fungal origin.

maintained by the International Centre for Diffraction Data (ICDD)

Structure Determination by Powder Diffraction - Database : methods, tutorials, references and links.

Archive of experimentally-determined, biological macromolecule 3-D structures from the Brookhaven National Laboratory. Also includes newsletters and a description of the PDB file format.
