nicotinamide/nicotinic acid mononucleotide adenylyltransferase catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP, and can also use the deamidated form, nicotinic acid mononucleotide (NaMN), as a substrate but with a lower efficiency
Nicotinamide/nicotinate mononucleotide adenylyltransferase, Eukaryotic; Nicotinamide/nicotinate mononucleotide (NMN/ NaMN)adenylyltransferase (NMNAT). NMNAT represents the primary bacterial and eukaryotic adenylyltransferases for nicotinamide-nucleotide and for the deamido form, nicotinate nucleotide. It is an indispensable enzyme in the biosynthesis of NAD(+) and NADP(+). Nicotinamide-nucleotide adenylyltransferase synthesizes NAD via the salvage pathway, while nicotinate-nucleotide adenylyltransferase synthesizes the immediate precursor of NAD via the de novo pathway. Human NMNAT displays unique dual substrate specificity toward both NMN and NaMN, and can participate in both de novo and salvage pathways of NAD synthesis. This subfamily consists strictly of eukaryotic members and includes secondary structural elements not found in all NMNATs.

nicotinate (nicotinamide) nucleotide adenylyltransferase; This model represents the predominant bacterial/eukaryotic adenylyltransferase for nicotinamide-nucleotide, its deamido form nicotinate nucleotide, or both. The first activity, nicotinamide-nucleotide adenylyltransferase (EC 2.7.7.1), synthesizes NAD by the salvage pathway, while the second, nicotinate-nucleotide adenylyltransferase (EC 2.7.7.18) synthesizes the immediate precursor of NAD by the de novo pathway. In E. coli, NadD activity is biased toward the de novo pathway while salvage activity is channeled through the multifunctional NadR protein, but this division of labor may be exceptional. The given name of this model, nicotinate (nicotinamide) nucleotide adenylyltransferase, reflects the lack of absolute specificity with respect to substrate amidation state in most species.

Phosphopantetheine adenylyltransferase; Phosphopantetheine adenylyltransferase (PPAT). PPAT is an essential enzyme in bacteria, responsible for catalyzing the rate-limiting step in coenzyme A (CoA) biosynthesis. The dinucleotide-binding fold of PPAT is homologous to class I aminoacyl-tRNA synthetases. CoA has been shown to inhibit PPAT and competes with ATP, PhP, and dPCoA. PPAT is a homohexamer in E. coli.

pantetheine-phosphate adenylyltransferase, bacterial; This model describes pantetheine-phosphate adenylyltransferase, the penultimate enzyme of coenzyme A (CoA) biosynthesis in bacteria. It does not show any strong homology to eukaryotic enzymes of coenzyme A biosynthesis. This protein was previously designated KdtB and postulated (because of cytidyltransferase homology and proximity to kdtA) to be an enzyme of LPS biosynthesis, a cytidyltransferase for 3-deoxy-D-manno-2-octulosonic acid. However, no activity toward that compound was found with either CTP or ATP. The phylogenetic distribution of this enzyme is more consistent with coenzyme A biosynthesis than with LPS biosynthesis.
