The invention provides a new, efficient method for the assembly of protein tertiary structure from known, loosely encoded secondary structure constraints and sparse information about exact side chain contacts. The method is based on a new method for the reduced modeling of protein structure and dynamics, where the protein is described by representing side chain centers of mass rather than alpha-carbons. The model has implicit, built-in multi-body correlations that simulate short- and long-range packing preferences, hydrogen bonding cooperativity, and a mean force potential describing hydrophobic interactions. Due to the simplicity of the protein representation and definition of the model force field, the Monte Carlo algorithm is at least an order of magnitude faster than previously published Monte Carlo algorithms for three-dimensional structure assembly. In contrast to existing algorithms, the new method requires a smaller number of tertiary constraints for successful fold assembly; on average, one for every seven residues as compared to one for every four residues. The reliability and robustness of the invention make it useful for routine application in model building protocols based on various (and even very sparse) experimentally-derived structural constraints.

The β-trefoil protein human fibroblast growth factor-1 (FGF-1) is made up of a six-stranded anti-parallel β-barrel closed off on one end by three β-hairpins, thus exhibiting a three-fold axis of structural symmetry. The N- and C-termini β-strands hydrogen bond to each other and are postulated from both NMR and X-ray structure data to represent a structurally-weakened region of the β-barrel. Val mutations within the N- and C-termini β-strands are shown to stabilize the structure and to increase van der Waals contacts by filling local cavities present within this region.

Surprisingly, several mutant polypeptides herein disclosed greatly exceed the wild-type polypeptide in ability to stimulate human fibroblasts to proliferate.
