Taurine mediates a plethora of membrane-linked effects in excitable tissues. To account for these multiple actions, four hypotheses have been proposed. One theory is based on the observation that taurine diminishes the inflammatory response of several cytotoxic oxidants. It is proposed that a reduction in the extent of membrane oxidative injury contributes(More)
Oyster shell protein and polyaspartate bound to calcite have been visualized at the atomic and molecular levels by atomic force microscopy. The identities of potential binding sites have been suggested from atomic force microscopy (AFM) images and have been evaluated by molecular modeling. Energies and conformations of binding to (110) and $$(1\bar 10)$$(More)
We investigate the initial stages of hen egg-white lysozyme (HEWL) adsorption at a charged solid interface using Brownian Dynamics simulation. The protein is modeled at the atomistic level and the adsorption surface is represented by a planar array of positively charged sites. Adsorption reactions are simulated at neutral pH and at low and high salt(More)
Quantum and statistical mechanics have been used to determine energy profiles for the SN2 reaction of Cl- + CH3Cl in the gas phase, in aqueous solution, and in liquid DMF. The energy profile in the gas phase has the characteristic double-well form featuring unsymmetrical ion-dipole complexes as minima and a symmetrical transition state. Hydration causes the(More)
Binding of citrate and phosphocitrate to calcium oxalate monohydrate crystals has been studied using scanning electron microscopy (SEM) and molecular modeling. Phosphocitrate structure has been resolved using low temperature X-ray analysis and ab initio computational methods. The (-1 0 1) crystal surface of calcium oxalate monohydrate is involved in binding(More)
