NAADP dinucleotide phosphate

NADP can be converted to nicotinic acid adenine dinucleotide phosphate (NAADP), which has distinct functions in the regulation of intracellular calcium stores. The studies of these new roles of NAD(P) in metabolism are in their early stages, but they might soon help to better understand and explain the symptoms of niacin deficiency ( pellagra) [1]. [Pg.851]

The nicotinamide nucleotide coenzymes function as electron carriers in a wide variety of redox reactions. In addition, NAD is the precursor of adenine dinucleotide phosphate (ADP)-ribose for ADP-ribosylation and poly(ADP-ribosylation) of proteins and cADP-ribose and nicotinic acid adenine dinucleotide phosphate (NAADP). They act as second messengers and stimulate increases in intracellular calcium concentrations. [Pg.200]

Exchange of the nicotinamide moiety of NADP for nicotinic acid, forming NAADP. Early studies also showed that the enzyme can catalyze exchange of nicotinamide with a variety of other bases, including histamine. Formation of histamine adenine dinucleotide phosphate was thought to provide an alternative to amine oxidase for rapid inactivation of histamine. [Pg.219]

NADI, the phosphorylated version of NAD, is converted in the cell to nicotinic acid adenine dinucleotide phosphate (NAADP). NAD cannot be used directly for this purpose. NAADP seems also to be used as a cell-signaling molecule, and to pnwokea burstof intracellular calcium ions (Aarhus ef ai, 1996 Dousa ct aL, 1996),... [Pg.597]
