Nicotinamide/nicotinic acid mononucleotide adenylyltransferase 3 (Nmnat3)

Catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP. Can also use the deamidated form; nicotinic acid mononucleotide (NaMN) as substrate with the same efficiency.

Can use triazofurin monophosphate (TrMP) as substrate. Can also use GTP and ITP as nucleotide donors.
