Folding pathway of a lattice model for protein folding
نویسندگان
چکیده
The folding of a protein-like heteropolymer is studied by direct simulation of a lattice model that folds rapidly to a well-defined “native” structure. The details of each molecular folding event depend on the random initial conformation as well as the random thermal fluctuations of the polymer. By analysing the statistical properties of hundreds of folding events, a classical folding “pathway” for such a polymer is found which includes partially folded, on-pathway intermediates that are shown to be metastable equilibrium states of the polymer. The folding reaction has a well-defined ensemble of transition state conformations that are characterized by common core structures. (January 4, 1998; Revised March 1, 1998)

متن کاملMaster equation of proteins in interaction with implicit or explicit solvent
Theoretical studies of protein folding on lattice models relie on the assumption that water close to amino-acids is always in thermal equilibrium all along the folding pathway. Within this framework, it has always been considered that out-of-equilibrium properties, such as folding time, could be evaluated equivalently from an averaging over a collection of trajectories of the protein with water...
متن کاملStructural Characteristics of Stable Folding Intermediates of Yeast Iso-1-Cytochrome-c
Cytochrome-c (cyt-c) is an electron transport protein, and it is present throughout the evolution. More than 280 sequences have been reported in the protein sequence database (www.uniprot.org). Though sequentially diverse, cyt-c has essentially retained its tertiary structure or fold. Thus a vast data set of varied sequences with retention of similar structure and fun...
متن کاملMatching Simulation and Experiment: a New Simpliied Model for Simulating Protein Folding (extended Abstract) a Simpliied Model for Protein Folding
Simulations of simpliied protein folding models have provided much insight into solving the protein folding problem. We propose here a new oo-lattice bead model, capable of simulating several diierent fold classes of small proteins. We present the sequence for an == protein resembling the IgG-binding proteins L and G. The thermodynamics of the folding process for this model are characterized us...
