Essential dynamics of proteins

Proteins: Structure, Function, and Bioinformatics, 1993
AbstractAnalysis of extended molecular dynamics (MD) simulations of lysozyme in vacuo and in aqueous solution reveals that it is possible to separate the configurational space into two subspaces: (1) an “essential” subspace containing only a few degrees of freedom in which anharmonic motion occurs that comprises most of the positional fluctuations; and

Protein Dynamism and Evolvability

Science, 2009
The traditional view that proteins possess absolute functional specificity and a single, fixed structure conflicts with their marked ability to adapt and evolve new functions and structures. We consider an alternative, “avant-garde view” in which proteins are conformationally dynamic and exhibit functional promiscuity.

Chaos in protein dynamics

Proteins: Structure, Function, and Genetics, 1997
MD simulations, currently the most detailed description of the dynamic evolution of proteins, are based on the repeated solution of a set of differential equations implementing Newton's second law. Many such systems are known to exhibit chaotic behavior, i.e., very small changes in initial conditions are amplified exponentially and lead to vastly ...

Dynamic personalities of proteins

Nature, 2007
Because proteins are central to cellular function, researchers have sought to uncover the secrets of how these complex macromolecules execute such a fascinating variety of functions. Although static structures are known for many proteins, the functions of proteins are governed ultimately by their dynamic character (or 'personality').

Dynamics of folded proteins

Nature, 1977
The dynamics of a folded globular protein (bovine pancreatic trypsin inhibitor) have been studied by solving the equations of motion for the atoms with an empirical potential energy function. The results provide the magnitude, correlations and decay of fluctuations about the average structure.

Protein-folding dynamics

Nature, 1976
In a discussion of the dynamics of protein folding two limiting models (random-search nucleation and chain propagation., diffusion–collision) are considered. It is suggested that the latter may have the dominant role in many proteins.

Protein dynamics of amelogenesis

The Anatomical Record, 1996
The synthesis, secretion, and fate of matrix proteins released by ameloblasts during enamel formation was studied in continuously erupting rat incisors.Computerized image processing was used to quantify silver grain distribution in radioautographs of sections prepared from rats injected with 3H-methionine, and this was correlated with fluorographs ...

Dynamic bond constraints in protein Langevin dynamics

The Journal of Chemical Physics, 2006
Bond constraint algorithms for molecular dynamics typically take, as the target constraint lengths, the values of the equilibrium bond lengths defined in the potential. In Langevin form, the equations of motion are temperature dependent, which gives the average value for the individual bond lengths a temperature dependence. In addition to this, locally

Dynamics of ESCRT proteins

Cellular and Molecular Life Sciences, 2012
Proteins of the ESCRT (endosomal sorting complex required for transport) complex function in membrane fission processes, such as multivesicular body (MVBs) formation, the terminal stages of cytokinesis, and separation of enveloped viruses from the plasma membrane.

Dynamic proteins in bacteria

Current Opinion in Microbiology, 2002
Growth of the bacterial cell involves proteins that assemble into dynamic localized structures that are required for cellular morphogenesis and division. During the past year, the continued application of fluorescence microscopy has led to the discovery of novel actin-like filaments involved in cell shape and plasmid DNA segregation, and to new ...
