Description and Uses
β-Nicotinamide adenine dinucleotide (NAD+) plays a major role in metabolism as a cofactor and mobile electron acceptor. NAD+ is a required oxidizing cosubstrate for many enzymes. It is reduced to NADH (Cat# N-035) which carries electrons to the electron transport chain for subsequent oxidative phorphorylation and ATP production. NAD+ is capable of donating ADP-ribose moieties to a protein, producing nicotinamide in the process. Sirtuin enzymes use NAD+ as a substrate to deacetylate proteins and direct activity between the nucleus and mitochondria. NAD+ is regenerated by fermentation and by oxidative phosphorylation.
β-Nicotinamide Adenine Dinucleotide is a coeznyme consisting of an adenine base and a nicotinamide base connected by a pair of bridging phosphate group. β-Nicotinamide Adenine Dinucleotide acts as a c oenzyme in redox reactions, as a donor of ADP-ribose moieties in ADP-ribosylation reactions and also as a precursor of the second messenger molecule cyclic ADP-ribose. β-Nicotinamide Adenine Dinucleot ide also acts as a substrate for bacterial DNA ligases and a group of enzymes called sirtuins that use NAD+ to remove acetyl groups from proteins.
