Genet. 38:779-786(2006). CC -!- FUNCTION: Catalyzes the condensation of iminoaspartate with CC dihydroxyacetone phosphate to form quinolinate. CC -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; pyridine-2,3- CC dicarboxylate from iminoaspartate: step 1/1. CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the quinolinate synthetase A family. Type 2 CC subfamily.
