Add experiment(s):


2-amino-3-carboxymuconate-6-semialdehyde→quinolinate + H+ + H2O (spontaneous)
No genes
Nicotinate-nucleotide diphosphorylase (carboxylating) (in reverse):
quinolinate + 2 H+ + 5-phospho-α-D-ribose 1-diphosphate→β-nicotinate D-ribonucleotide + CO2 + diphosphate (EC 2.4.2.19)

Candidate genes for each reaction are identified from best hits to MetaCyc; by matching EC numbers (which are assigned by TIGRFam, SEED, or best hits to KEGG); or by matching SEED roles to KEGG reactions to MetaCyc reactions. See the "Protein" tab of each gene for more information
