Application

7-Diethylamino-3-[N-(2-maleimidoethyl)carbamoyl]coumarin is utilized as a fluoresencent biological sensing device . Used for real-time measurements for the release of inorganic phosphates during enzymatic reaction when MDCC is conjugated to a mutant phosphate-binding protein . Also, utilized for intramolecular fluorescence energy transfer (FRET) experiments .

We show that T7 DNA polymerase exists in three distinct structural states, as reported by a conformationally sensitive fluorophore attached to the recognition (fingers) domain. The conformational change induced by a correct nucleotide commits the substrate to the forward reaction

1. The rate of appearance of inorganic phosphate (Pi) and hence the ATPase activity of rabbit psoas muscle in single permeabilized muscle fibres initially in rigor was measured following laser flash photolysis of the P3-1-(2-nitrophenyl)ethyl ester of ATP (NPE-caged ATP)

Biochemistry, 33(27), 8262-8271 (1994-07-12)
A probe has been developed that can rapidly measure micromolar concentrations of inorganic phosphate (Pi), in particular to follow the release of Pi in real time from enzymes such as phosphatases. Its application is described to investigate the mechanism of

A sensing system for nickel based on the nickel binding protein (NBP) from Escherichia coli is shown to be feasible. The versatility of NBP was demonstrated by its use in three different assay formats. When the NBP binds nickel, it

This communication describes the development of a thiamin sensor based on the bacterial thiamin binding protein. A triple mutant (C48S, C50S, S62C) of TbpA was labeled on C62 with N-[2-(L-maleimidyl)ethyl]-7-(diethylamino)coumarin-3-carboxamide (MDCC). Thiamin binding to this protein reduced the coumarin fluorescence
