CC Evidence={ECO:0000256|HAMAP-Rule:MF_00110};
CC Note=Binds 1 divalent metal cation per subunit. Can use either Co(2+)
CC or Zn(2+). {ECO:0000256|HAMAP-Rule:MF_00110};
CC -!- COFACTOR:
CC Name=NAD(+); Xref=ChEBI:CHEBI:57540;
CC Evidence={ECO:0000256|ARBA:ARBA00001911,
CC ECO:0000256|HAMAP-Rule:MF_00110};
CC -!- PATHWAY: Metabolic intermediate biosynthesis; chorismate biosynthesis;
CC chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step
CC 2/7. {ECO:0000256|HAMAP-Rule:MF_00110}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00110}.
CC -!- SIMILARITY: Belongs to the sugar phosphate cyclases superfamily.
CC Dehydroquinate synthase family. {ECO:0000256|HAMAP-Rule:MF_00110}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00110}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
