    摘要: A method for identifying active site inhibitors of scission enzyme that cleaves the backbones or side groups of peptides, and for using the resultant inactivators to inhibit the target scission enzyme. Kinetic assays are employed to identify peptide substrates that tightly bind to the active site of the target protease but that are not easily cleaved. These noncleavable but tightly binding substrates are optionally structurally modified to yield inhibitory compounds with optimized properties. Additionally these substrates exhibit apparent specificity for a transition state or ground state configuration of the protease.

    摘要: A sensor for detecting an analyte in an environment includes a first reaction system including a first enzyme and a substrate for the first enzyme. The analyte inhibits the reaction of the substrate catalyzed by the first enzyme. The sensor further includes at least a second reaction system that reacts to produce a first detectable state when the first enzyme is inhibited. In some embodiments, the reaction of the first reaction system can produce a second detectible state, different from the first detectible state. Another sensor for detecting an analyte in an environment includes a first reaction system including a first enzyme or a first substrate for the first enzyme. In this embodiment, the analyte is either a substrate for the first enzyme or the first enzyme if the first reaction system includes the first substrate. Figure (1) illustrates reaction schematics of one embodiment of a sensor of the present invention for detecting nerve agents.

    摘要: Systems, including compositions and methods, for measuring pH, particularly in cells, organelles, and other samples. The compositions include pH-sensitive fluorescent and fluorogenic 2',7'-dialkylfluorescein derivatives and associated nonfluorescent precursor compounds of the formula shown below. The compositions may permit ratiometric measurement in the excitation spectrum and the emission spectrum. The methods include adding a precursor compound to a sample cell, incubating the sample cell to release the free indicator, illuminating the sample cell, and detecting the fluorescence response of the free indicator.
