CC -!- FUNCTION: Catalyzes the condensation of iminoaspartate with
CC dihydroxyacetone phosphate to form quinolinate. {ECO:0000255|HAMAP-
CC Rule:MF_00567}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=dihydroxyacetone phosphate + iminosuccinate = H(+) + 2 H2O +
CC phosphate + quinolinate; Xref=Rhea:RHEA:25888, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:29959, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:57642, ChEBI:CHEBI:77875; EC=2.5.1.72;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00567};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:25889;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00567};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00567};
CC Note=Binds 1 [4Fe-4S] cluster per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00567};
CC -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from
CC iminoaspartate: step 1/1. {ECO:0000255|HAMAP-Rule:MF_00567}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00567}.
CC -!- SIMILARITY: Belongs to the quinolinate synthase family. Type 1
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00567}.
