Description_x000D_ General description_x000D_ Nicotinic acid mononucleotide (NaMN) is formed from nicotinic acid 5-phosphoribosyl-1-pyrophosphate (PRPP) in the Preiss-Handler pathway in the presence of enzyme phosphoribosyltransferase (NaPRT)._x000D_ Application_x000D_ Nicotinic acid mononucleotide has been used as a substrate for NMN/NaMN adenylyltransferase (NMNAT) during nicotinamide adenine dinucleotide (NAD) biosynthesis._x000D_ Packaging_x000D_ 10, 25, 100 mg in poly bottle_x000D_ 5 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ Nicotinic acid mononucleotide (NaMN) may be used to study the relationship between the phosphate-responsive signaling (PHO) pathway and nicotine adenine dinucleotide (NAD(+)) metabolism in yeast. Nicotinate mononucleotide is a substrate for NMN/NaMN adenylyltransferase (NMNAT) and nicotinate mononucleotide adenylyltransferase. NaMN amidation results in the synthesis of nicotinamide mononucleotide(NMN), which is further converted to NAD cofactor.
