Discrete breathers in a realistic coarse-grained model of proteins.
We report the results of molecular dynamics simulations of an off-lattice protein model featuring a physical force-field and amino-acid sequence. We show that localized modes of nonlinear origin, discrete breathers (DBs), emerge naturally as continuations of a subset of high-frequency normal modes residing at specific sites dictated by the native fold. DBs are time-periodic, space-localized vib...
متن کاملExact Energy Landscapes of Proteins Using a Coarse-Grained Model
The understanding of the relation between the amino acid sequence and the spatial structure of the protein is an open task since many decades. Some tools for the prediction of protein structures from known ones were developed, but they let unanswered fundamental questions about properties of folded proteins and the folding process itself. Recently, coarse-grained models were developed, which ar...
متن کاملCoarse-grained entropy and stimulated emission in curved space-time.
We study the entropy generation and particle production in scalar quantum field theory in expanding spacetimes with many-particle mixed initial states. The recently proposed coarse-grained entropy approach by Brandenberger et al. is applied to systems which may have a non-zero initial entropy. We find that although the particle production is amplified as a result of boson statistics, the (coars...
متن کاملHighly Coarse-Grained Representations of Transmembrane Proteins
Numerous biomolecules and biomolecular complexes, including transmembrane proteins (TMPs), are symmetric or at least have approximate symmetries. Highly coarse-grained models of such biomolecules, aiming at capturing the essential structural and dynamical properties on resolution levels coarser than the residue scale, must preserve the underlying symmetry. However, making these models obey the ...
متن کاملA coarse-grained model for DNA origami
Modeling tools provide a valuable support for DNA origami design. However, current solutions have limited application for conformational analysis of the designs. In this work we present a tool for a thorough study of DNA origami structure and dynamics. The tool is based on a novel coarse-grained model dedicated to geometry optimization and conformational analysis of DNA origami. We explored the...
