Journal ArticleDOI
TL;DR: A new formulation for a dihedral angle autocorrelation function is introduced and applied to study side-chain dynamics in L-Enk, finding that the side- chain dynamics of the large Tyr and Phe residues cannot be adequately sampled in 2.0-ns simulations, while this does seem to be possible for the smaller Leu side chain.

TL;DR: In this paper, the ruthenium and osmium complexes were prepared according to literature procedures, and the DCPD was purchased from Fluka, and technical quality, 94%, from Shell and used as received.
Abstract: The ruthenium and osmium complexes were prepared according to literature procedures [ l l ] . NBE was purchased from Fluka, and DCPD (technical quality, 94%) from Shell and used as received. Viscosimetric measurements were performed on a home-built, real-time viscosimeter. Gel times were recorded on a Brookfield viscosimeter, DSCs on a Mettler DSC30 with a Mettler TCll controller, TGAs on a Mettler TG50 with a Mettler TCfOA controller, and surface roughness on a Form Talysurf S3C-50. Micro hardness was determined on a Fischerscope H100. I3C CP-MAS NMR spectra of a piece of poly(DCPD) that was tightly fitted into the spinner were recorded on a Bruker 400-MHz instrument with a MAS rate of 11 kHz and a pulse delay of 5 s (a pulse delay of 60 s gave an identical result).

TL;DR: This study compares HINT scores that are based upon experimentally and thermodynamically derived measurements with experimentally determined thermodynamic results to provide a framework for understanding subunit stabilities based upon individual atom interactions and repulsions in hemoglobin.

Journal ArticleDOI
TL;DR: The hypothesis that hydration of an interfacial cavity functions as a non-covalent extension of the DNA surface is supported andereo-specific interrogation of bound water by chemical synthesis provides a general method to assess the coupling between solvation and DNA recognition.
