Application
β-Nicotinamide adenine dinucleotide (NAD+) and β-Nicotinamide adenine dinucleotide, reduced (NADH) comprise a coenzyme redox pair (NAD+:NADH) involved in a wide range of enzyme catalyzed oxidation reduction reactions. In addition to its redox function, NAD+/NADH is a donor of ADP-ribose units in ADP-ribosylaton (ADP-ribosyltransferases; poly(ADP-ribose) polymerases ) reactions and a precursor of cyclic ADP-ribose (ADP-ribosyl cyclases
As a reagent, NADH can be used in enzyme cycling assays to amplify detection of activity of biologically relevant enzymes or metabolites present in low concentrations
Biochem/physiol Actions
NADH is a coenzyme that functions as a regenerating electron donor in catabolic processes including glycolysis, β-oxidation and the citric acid cycle (Krebs cycle, TCA cycle). It participates in cell signaling events as well, for example as a substrate for the poly (ADP-ribose) polymerases (PARPs) during the DNA damage response. The NAD+/NADH dependent sirtuins play key roles in stress responses during events involving energy metabolism, with implications in cancer biology, diabetes and eurodegenerative disease
