Reciprocal Net is funded by the U.S. National Science Foundation as part of the National Science Digital Library project.  NSDL Logo
2021 - The Protein Data Bank Turns 50!

The Protein Data Bank (PDB) archive turns 50 this year. Congratulations and thank you. The PDB archives macromolecular structural data and makes them freely available to the global community. Symposia are planned to celebrate this milestone. Detailed information is available at https://foundation.wwpdb.org/pdb50.html"

Welcome to Reciprocal Net

The Reciprocal Net is a distributed database used by research crystallographers to store information about molecular structures; much of the data is available to the general public. The Reciprocal Net project is still under development. Currently, we have 18 participating crystallography laboratories online. The project is funded by the National Science Foundation (NSF) and part of the National Science Digital Library. More about Reciprocal Net.
