RL   Submitted (MAR-2003) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Involved in the third step of the chorismate pathway, which
CC       leads to the biosynthesis of aromatic amino acids. Catalyzes the cis-
CC       dehydration of 3-dehydroquinate (DHQ) and introduces the first double
CC       bond of the aromatic ring to yield 3-dehydroshikimate.
CC       {ECO:0000255|HAMAP-Rule:MF_00214}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=3-dehydroquinate = 3-dehydroshikimate + H2O;

CC         Rule:MF_00214};
CC   -!- PATHWAY: Metabolic intermediate biosynthesis; chorismate biosynthesis;
CC       chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step
CC       3/7. {ECO:0000255|HAMAP-Rule:MF_00214}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00214}.
CC   -!- SIMILARITY: Belongs to the type-I 3-dehydroquinase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00214}.
