Defining Long-Range Order and Local Disorder in Native α-Synuclein Using Residual Dipolar CouplingsCited by: For a residues-long polypeptide with a real molecular mass of 11 kDa, the apparent molecular mass of a molten globular conformation estimated from the hydrodynamic data (e.g. gel-filtration) is 16 kDa, for the native pre-molten globule this number is 29 kDa, whereas for the native coil the column will give ∼40 by:
Research in the Garcia-Garibay group is based on a deep knowledge of molecular and supramolecular structure to addresses questions of chemical reactivity and molecular dynamics in the solid state. By controlling reactivity and motion, they are able to engineer reactions in crystals, develop green chemical processes, and, with fine-tuned. Results and discussion. We here present crystal structures of the oxidized ligand-free ( Å) and reduced ligand-free ( Å), OCPA-bound ( Å) and DNA-bound ( Å) D. hafniense CprK in addition to an intermediate OCPA-bound structure obtained by soaking ligand-free crystals ( Å) (Fig. 1).These structures are described in more detail below, and serve as the basis for Cited by:
Proteins are frequently characterized as molecular machines, with atomic-level motions driving biological function. Past decades have witnessed a dramatic increase in the tools available to probe these dynamics, but few methods enable us to resolve these collective motions with high spatial resolution. Isomerization is accompanied by a large photo-induced molecular motion, which is able to significantly affect the physical and chemical properties of the materials in which they are incorporated. In some material systems, the nanoscopic structural movement of the isomerizing azobenzene molecules can be even propagated at macroscopic spatial scales.

The rod-like molecule bis((4-(4-pyridyl)ethynyl)bicyclooctyl)buta-1,3-diyne, 1, contains two 1,4-bis(ethynyl)bicyclooctane (BCO) chiral rotators linked by a diyne fragment and self-assembles in a one-dimensional, monoclinic C2/c centrosymmetric structure where two equilibrium positions with large occupancy imbalance (88% versus 12%) are identified on a Cited by: TMHR.

σ is a member of a highly conserved family of proteins that has a double-edged sword role in human cancers. Former reports have indicated that the protein may be in an open or closed state.
In this work, we found that the apoσ is in an open state compared with the phosphopeptide bound σ complex which is in a more closed state based on our Cited by: The phosphorylated kinase-inducible activation domain (pKID) adopts a helix–loop–helix structure upon binding to its partner KIX, although it is unstructured in the unbound state.
The N-terminal and C-terminal regions of pKID, which adopt helices in the complex, are called, respectively, αA and αB. We performed all-atom multicanonical molecular dynamics simulations of pKID with Cited by: Orientational order should increase as temperature is reduced This modulus is the response of the smectic layers and corresponds to the compression modulus B of low molar mass liquid crystals.
Above this deformation, the smectic structure breaks down, as indicated by the lower modulus. the molecular motion becomes less and the. Nematic order, in the bulk or at interfaces, is ubiquitous for semiflexible conjugated polymers.
Nevertheless, the effect of liquid crystalline order on charge transport remains unclear. Using an analytical model, we demonstrate that nematic order leads to an enhancement in charge mobilities when compared to isotropic chains.
Furthermore, we predict a quadratic Cited by: 5. X-ray crystallography (XRC) is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions.
By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the. Meanwhile, Targacept has considered the fact that mecamylamine is a racemic mixture of two enantiomers (namely, the S-enantiomer, TC, and the R-enantiomer, TC) and that the α4β2 nAChR Cited by:.
Diffuse scattering is caused by correlated motions in protein crystals and is a potential source of information on protein dynamics. Although internal motional models were able to reproduce the diffuse scattering to a limited extent in earlier research, it is shown here that by far the most dominant contribution is from rigid-body translations, with internal motions contributing only a Cited by: 4.This review examines low-frequency vibrational modes of proteins and their coupling to enzyme catalytic sites.
That protein motions are critical to enzyme function is clear, but the kinds of motions present in proteins and how they are involved in function remain unclear. Several models of enzyme-catalyzed reaction suggest that protein dynamics may be involved in the chemical .Conformational Entropy of FK Binding to FKBP12 Determined by Nuclear Magnetic Resonance Relaxation and Molecular Dynamics SimulationsCited by: 1.
