|Nicotinate-nucleotide diphosphorylase (carboxylating).
|Nicotinate-nucleotide pyrophosphorylase (carboxylating).|
|Quinolinate phosphoribosyltransferase (decarboxylating).|
|Beta-nicotinate D-ribonucleotide + diphosphate + CO(2) <=> pyridine-2,3-dicarboxylate + 5-phospho-alpha-D-ribose 1-diphosphate|
- The reaction is catalyzed in the opposite direction.
- Since quinolinate is synthesized from L-tryptophan in eukaryotes,
but from L-aspartate in some prokaryotes, this is the first NAD(+)
biosynthesis enzyme shared by both eukaryotes and prokaryotes.
