JStruct is an open source stand-alone software tool designed and developed by Just Biotherapeutics for the storage and retrieval of public and proprietary three-dimensional macromolecular structures as well as information parsed from their content.


JStruct provides a robust and secure means to store, access, search and utilize both public and proprietary structures within the same system. With JStruct it is possible to search, calculate and compare structures across a full set of files while keeping internal sequences from being publicly exposed.

The JStruct open source code is available via Bitbucket and is licensed under the GNU General Public License.
