Simulations of Protein Folding
A protein is a linear chain of amino acids. The proteins of natural living organisms are composed of 20 different types of amino acids. A typical protein is a polymer of 300 amino acids, of which there are 20 = 2× 10 different possibilities. The human body uses about 80,000 different proteins for most of its functionality, including structure, communication, transport, and catalysis. The order ...

Title of dissertation: COMPUTER SIMULATIONS OF PROTEIN FOLDING Aram Davtyan, Doctor of Philosophy, 2013 Dissertation directed by: Professor Garegin A. Papoian Department of Chemistry and Institute for Physical Science and Technology Understanding how proteins fold and interact with each other is key to understanding virtually all biological processes. Recent advances in computer power and model...
متن کاملComputer Simulations of Protein Folding
Computer simulation holds great promise to significantly complement experiment as a tool for biological and biophysical characterization. Simulations offer the promise of atomic spatial detail with femtosecond temporal resolution. However, the application of computational methodology has been greatly limited due to fundamental computational challenges: put simply, for much of what one would wan...
متن کاملForce field bias in protein folding simulations.
Long timescale (>1 micros) molecular dynamics simulations of protein folding offer a powerful tool for understanding the atomic-scale interactions that determine a protein's folding pathway and stabilize its native state. Unfortunately, when the simulated protein fails to fold, it is often unclear whether the failure is due to a deficiency in the underlying force fields or simply a lack of suff...
متن کاملGenetic algorithms for protein folding simulations.
Genetic algorithms methods utilize the same optimization procedures as natural genetic evolution, in which a population is gradually improved by selection. We have developed a genetic algorithm search procedure suitable for use in protein folding simulations. A population of conformations of the polypeptide chain is maintained, and conformations are changed by mutation, in the form of conventio...
