This approach to protein simulation uses Protein Data Bank information to construct useful, simple, geometric constraints that can be applied to a protein simulation. We compiled experimental data for proteins with between 30-90 residues and analyzed the relationship between their sizes, defined as the radius of a sphere that encloses the 3D structure; the maximum distance between any two residues and the number of residues in the protein. A significant relationship was found and the analysis was used to predict the ranges that the size and maximum distance between residues would have for a protein with a given number of residues. These ranges were used to constrain folding from secondary structures for proteins IROP and IHDD and, using a random path planning approach, produced results that were not terribly accurate, but quite fast, suggesting that the constraint would be most useful as an inexpensive addition to an existing technique.
