comment
  • FUNCTION Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate.CATALYTIC ACTIVITY iminosuccinate + dihydroxyacetone phosphate = quinolinate + phosphate + 2 H2O + H(+)COFACTOR Binds 1 [4Fe-4S] cluster per subunit.PATHWAY Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from iminoaspartate: step 1/1.SUBUNIT Homodimer.SUBCELLULAR LOCATION Belongs to the quinolinate synthase family. Type 1 subfamily.
