Gene
NAPRT2
Protein
Nicotinate phosphoribosyltransferase 2
Organism
Arabidopsis thaliana
Length
557 amino acids
Function
Catalyzes the first step in the biosynthesis of NAD from nicotinic acid, the ATP-dependent synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate. Helps prevent cellular oxidative stress via its role in NAD biosynthesis.
Similarity
Belongs to the NAPRTase family.
