Urea orientation at protein surfaces.
Urea facilely denatures proteins in aqueous solution. Despite its extensive use, the molecular mechanism of this process remains unclear.1,2 Most of the literature in this area can be summarized into two major models: the direct mechanism and the indirect mechanism. According to the direct mechanism, urea can “bind” to proteins through hydrogen bonding and/or other electrostatic interactions. B...
متن کاملReactivities of Actin as a Contractile Protein
The molecular basis for the mechanism of contraction in striated muscle, with primary emphasis on the interaction between the thick and thin filaments and the role of the thin (actin) filaments, is the theme presented. Recent information relating to actin-myosin interaction points up the fact that definitive statements cannot be made regarding the molecular interaction(s) that lead to contracti...
متن کاملCollisions of ultracold 23Na87Rb molecules with controlled chemical reactivities
The collision of molecules at ultracold temperatures is of great importance to understand the chemical interactions at the quantum regime. Although much theoretical work has been devoted to this, experimental data are only sparsely available, mainly because of the difficulty in producing ground-state molecules at ultracold temperatures. We report here the creation of optically trapped samples o...
متن کاملAdsorption of allergen protein at surfaces
Cleaning of processing equipment in the food industry and of surfaces in catering and domestic environments is a key issue in prevention of accidental exposure of individuals with food allergy to allergenic foods. Despite this, little systematic work has been carried out understanding adsorption processes and the effectiveness or otherwise of cleaning procedures. The limiting factor in studying...
متن کاملRelaxations of methylpyridinone tautomers at the C60 surfaces: DFT studies
Density functional theory (DFT) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1H)–one (MPO), as a representative of pyridinone derivatives, at the fullerene (C60) surfaces. Optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (CQ) have been e...
