    A Semisynthetic Fluorescent Sensor Protein for Glutamate
    摘要:
    We report the semisynthesis of a fluorescent glutamate sensor protein on cell surfaces. Sensor excitation at 547 nm yields a glutamate-dependent emission spectrum between 550 and 700 nm that can be exploited for ratiometric sensing. On cells, the sensor displays a ratiometric change of 1.56. The high sensitivity toward glutamate concentration changes of the sensor and its exclusive extracellular localization make it an attractive tool for glutamate sensing in neurobiology.

    Fluorescent probes based on N-heterocyclic bisphosphonates or their phosphonocarboxylate analogues are provided. The probes have variable spectroscopic properties, bone mineral binding affinities, and pharmacological activities. Methods for preparing the probes include the use of two complementary linking strategies, one involving an amino group and the other involving a chloride group as a precursor to an amino group. In other versions, bifunctional N-heterocyclic bisphosphonates are provided having an amino group and an azido group as linking moieties. In some versions, the linking chemistry allows attachment of a wide selection of fluorescent dyes in the visible to near-infrared range to any of three clinically important heterocyclic bisphosphonates.

    Commercially available 2′-O-pivaloyloxymethyl (PivOM) phosphoramidites were employed in an SPS protocol for RNA 5′ azides. The utility of the N3-RNAs in CuAAC and SPAAC was demonstrated by RNA 5′ labeling, chemical ligation including fragment joining and cyclization, and bioconjugation. As a result, several new RNA conjugates that may be valuable tools for studies on biological events such as innate

    attachment of the dyes was accomplished by 1,3‐dipolar cycloaddition between alkynes and azides (‘click’ reaction) and is a prime example for a novel class of sensor constructs. Especially, the attachment of two (different) fluorophores on opposite sides of the molecular rods paves the way to new sensor systems with less bulky (compared to the conventional DNA‐ or protein‐based concepts), nevertheless rigid

    Methods and reagents for site-selective functionalization of peptides and proteins. The methods most generally involve the reaction of a thioester with hydrazine. Reagents include bifunctional reagents of formula: H 2 N—NH—CH 2 -M-L-FG and salts thereof where M is a single bond or a chemical group carrying a non-bonding electron pair, such as —C(O)NR′—, where R′ is H, or an alkyl or aryl group; L is an optional linker group as described above; and FG is a functional group having reactivity that is orthongonal to that of the hydrazine group. FG can, among others, be an azide, alkenyl, alkynyl, nitrile (—CN) or triazole group and is preferably an azide group (—N 3 ). Methods and reagents can, for example, be combined with intein-mediated protein splicing to link proteins or fragments thereof to various chemical species or to a surface. Surface immobilization of proteins via the methods herein results in immobilized proteins which substantially retain biological activity and is thus useful for the generation of peptide or protein microarrays. Kits for functionalization and/or immobilization of peptides and proteins are provided as well as microarrays of peptides, proteins or both.
