权利人:UMICORE AG & CO KG
摘要:The invention provides methods for a one-pot synthesis of molecular sieves of the CHA-type. The method uses molecular and non-molecular sieves as sources of silicon and aluminum. A first OSDA is selected from tetraethylenepentamine (TEPA) and triethy-lenepentamine (TETA). The synthesis mixture comprises a first metal selected from copper, iron and zinc. Optionally, the synthesis mixture may furthermore comprise a second OSDA and/or a second metal selected from manganese, cesium, magnesium, calcium, strontium, barium, yttrium, titanium, zirconium, niobium, iron, zinc, silver, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and mixtures thereof. The molecular sieves of the CHA-type obtainable by the method can be used as SCR-catalytically active substances for the removal of nitrogen oxides from exhaust gases of combustion engines.

标题:Lipid matrix-assisted chemical ligation and synthesis of membrane polypeptides

摘要:The present invention relates to methods and compositions for lipid matrix-assisted chemical ligation and synthesis of membrane polypeptides that are incorporated in a lipid matrix. The invention is exemplified in production of a prefolded membrane polypeptide embedded within a lipid matrix via stepwise chemoselective chemical ligation of unprotected peptide segments, where at least one peptide segment is embedded in a lipid matrix. Any chemoselective reaction chemistry amenable for ligation of unprotected peptide segments can be employed. Suitable lipid matrices include liposomes, micelles, cell membrane patches and optically isotropic cubic lipidic phase matrices. Prefolded synthetic and semi-synthetic membrane polypeptides synthesized according to the methods and compositions of the invention also permit site-specific incorporation of one or more detectable moieties, such as a chromophore, which can be conveniently introduced during synthesis. The methods and compositions of the invention have multiple uses. For example, they can be used to assay ligand binding to membrane polypeptides and domains comprising a receptor, and thus are extremely useful for structure/function studies, drug screening/selection/design, and diagnostics and the like, including high-throughput applications. The methods and compositions of the invention are particularly suited for FRET analyses of previously inaccessible membrane polypeptides.
