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}.
