PSI researchers are characterizing domains of unknown function in microbes, and discovering new protein folds in the process.

The Structural Biology Knowledgebase (SBKB) is a free,
comprehensive resource produced in a collaboration between the
Protein Structure Initiative (PSI) and Nature Publishing Group (NPG)...
The PSI is a federal, university, and industry effort aimed at
dramatically reducing the costs and lessening the time it takes to
determine a three-dimensional protein structure.
