Diffusion-collision model algorithms for protein folding kinetics

Abstract

The diffusion-collision model (DCM) of protein folding is described qualitatively and quantitatively. The input parameters required to perform a calculation are explained, and the output data are outlined. Three examples are given of calculating DCM folding kinetics: the Engrailed Homeodomain (a three-helix bundle with three helical microdomains, pdb code 1ENH), protein G (with three microdomains having a beta-hairpin-alpha-helix-beta-hairpin motif, pdb code 1PGA), and apomyoglobin (with eight helices and seven strong microdomain-microdomain pairings).
