Heteronuclear 2-dimensional NMR was used to correlate the 1H and 31P chem. shifts of cellular phosphates. Exptl. spectra agree with theor. predictions based on a novel approach using subspectral anal. The spectra are sensitive to the homonuclear scalar cou ...
Absorption, fluorescence and excitation spectra of three-dimensional bacteriorhodopsin crystals harvested from a lipidic cubic phase are presented. The combination of the spectroscopic expts. performed at room temp., controlled pH and full external hydrati ...
This thesis describes the application of the quantum mechanics/molecular mechanics (QM/MM) Car-Parrinello methodology to two systems of high biological interest: (a) The potassium channel KcsA from Streptomyces lividans and (b) The DNA repair enzyme EndoIV ...
Rigid p-octiphenyl rods were used to create helical tetrameric p-stacks of blue, red-fluorescent naphthalene diimides that can span lipid bilayer membranes. In lipid vesicles containing quinone as electron acceptors and surrounded by ethylenediaminetetraac ...
Proton insertion in polycryst. tungsten oxide has been studied with photoelectron spectroscopy and semi-empirical calcns. The W 4f spectra show growth of W5+ and W4+ oxidn. states as a function of inserted proton content in the crystal lattice. A concomita ...
In this study, we report that intercalation of tin into montmorillonite clay (Sn‐MMT) boosts catalytic activity for the synthesis of polyoxymethylene dimethyl ethers, a promising diesel fuel additive. This increase in activity is attributed to the formatio ...
Members of the newly discovered glycoprotein-associated amino acid transporter family (gpaAT-family) share a similar primary structure with >40% identity, a predicted 12-transmembrane segment topology and the requirement for association with a glycoprot ...
