Abstract

The invention relates to the in vitro and in cellulo detection of the cofactors nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Provided is a sensor molecule for fluorescence or luminescence-based detection of a nicotinamide adenine dinucleotide analyte, in particular for detecting the concentrations of NAD+, NADP' and/or the ratios of the concentrations of NAD '/NAD H and NADP '/NADPH, the sensor comprising (i) a binding protein (BP) for the nicotinamide adenine dinucleotide analyte, the BP being derived from sepiapterin reductase (SPR; EC 1.1.1.153) (ii) a SPR ligand (SPR-L) capable of intramolecular binding to said BP in the presence of the oxidized form of said analyte; and (iii) at least one fluorophore.

Nicotinamide adenine dinucleotide

Nicotinamide adenine dinucleotide (NAD) is a coenzyme central to metabolism. Found in all living cells, NAD is called a dinucleotide because it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine nucleobase and the other, nicotinamide. NAD exists in two forms: an oxidized and reduced form, abbreviated as NAD and NADH (H for hydrogen), respectively.

Flavin adenine dinucleotide

In biochemistry, flavin adenine dinucleotide (FAD) is a redox-active coenzyme associated with various proteins, which is involved with several enzymatic reactions in metabolism. A flavoprotein is a protein that contains a flavin group, which may be in the form of FAD or flavin mononucleotide (FMN). Many flavoproteins are known: components of the succinate dehydrogenase complex, α-ketoglutarate dehydrogenase, and a component of the pyruvate dehydrogenase complex.

Nicotinamide adenine dinucleotide phosphate

Nicotinamide adenine dinucleotide phosphate, abbreviated NADP or, in older notation, TPN (triphosphopyridine nucleotide), is a cofactor used in anabolic reactions, such as the Calvin cycle and lipid and nucleic acid syntheses, which require NADPH as a reducing agent ('hydrogen source'). NADPH is the reduced form of NADP, the oxidized form. NADP is used by all forms of cellular life. NADP differs from NAD by the presence of an additional phosphate group on the 2' position of the ribose ring that carries the adenine moiety.
