  The present invention provides clostridial toxin substrates useful in assaying for the protease activity of any clostridial toxin, including botulinum toxins of all serotypes as well as tetanus toxins. A clostridial toxin substrate of the invention contains a lanthanide donor fluorophore; an acceptor having an absorbance spectrum overlapping the emission spectrum of the lanthanide donor fluorophore; and a clostridial toxin recognition sequence that includes a cleavage site, where the cleavage site intervenes between the lanthanide donor fluorophore and the acceptor and where, under the appropriate conditions, resonance energy transfer is exhibited between the lanthanide donor fluorophore and the acceptor.

  本发明提供的梭菌毒素底物可用于检测任何梭菌毒素的蛋白酶活性，包括所有血清型的肉毒杆菌毒素和破伤风毒素。本发明的梭菌毒素底物包含一个镧系供体荧光团；一个受体，其吸收光谱与镧系供体荧光团的发射光谱重叠；以及一个梭菌毒素识别序列，该序列包括一个裂解位点，裂解位点位于镧系供体荧光团和受体之间，在适当条件下，镧系供体荧光团和受体之间会发生共振能量转移。

  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.
