Nicotinate-nucleotide pyrophosphorylase [carboxylating]
Nicotinate-nucleotide adenylyltransferase
Adenosine triphosphate + Ammonium + Nicotinic acid adenine dinucleotide → Adenosine monophosphate + Hydrogen Ion + NAD + Pyrophosphate
Adenosine triphosphate + L-Glutamine + Nicotinic acid adenine dinucleotide + Water → Adenosine monophosphate + Hydrogen Ion + L-Glutamic acid + NAD + Pyrophosphate
Adenosine triphosphate + Hydrogen Ion + nicotinate β-D-ribonucleotide → Nicotinic acid adenine dinucleotide + Pyrophosphate
Hydrogen Ion + Phosphoribosyl pyrophosphate + Quinolinic acid → Carbon dioxide + Pyrophosphate + nicotinate β-D-ribonucleotide
Dihydroxyacetone phosphate + Iminoaspartic acid → Phosphate + Quinolinic acid + 2 Water
L-Aspartic acid + Oxygen → Hydrogen Ion + Hydrogen peroxide + Iminoaspartic acid
NAD + Water → Adenosine monophosphate + Nicotinamide ribotide
Nicotinamide ribotide + Water → Nicotinamide riboside + Phosphoric acid
Nicotinamide riboside + Phosphoric acid ↔ Niacinamide + Ribose 1-phosphate
1-Methylnicotinamide + Oxygen + Water → Hydrogen Ion + Hydrogen peroxide + N1-Methyl-2-pyridone-5-carboxamide
Hydrogen Ion + Niacinamide + S-Adenosylmethionine → 1-Methylnicotinamide + S-Adenosylhomocysteine
