CC   -!- FUNCTION: Catalyzes the condensation of iminoaspartate with
CC       dihydroxyacetone phosphate to form quinolinate.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=dihydroxyacetone phosphate + iminosuccinate = H(+) + 2 H2O +
CC         phosphate + quinolinate; Xref=Rhea:RHEA:25888, ChEBI:CHEBI:15377,

CC         ChEBI:CHEBI:57642, ChEBI:CHEBI:77875; EC=2.5.1.72;
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:25889;
CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC       Note=Binds 1 [4Fe-4S] cluster per subunit.;
CC   -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from
CC       iminoaspartate: step 1/1.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- SIMILARITY: Belongs to the quinolinate synthase family. Type 1
CC       subfamily.
