PSI researchers have discovered that protein flexibility is a key element in the evolutionary pathway for developing photoconvertable GFP-like proteins.

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.
