CC       Note=Binds 1 [4Fe-4S] cluster per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_00569};
CC   -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from
CC       iminoaspartate: step 1/1. {ECO:0000255|HAMAP-Rule:MF_00569}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00569}.
CC   -!- SIMILARITY: Belongs to the quinolinate synthase family. Type 3
