CC -!- FUNCTION: Is involved in the catabolism of quinate. Allows the
CC utilization of quinate as carbon source via the beta-ketoadipate
CC pathway. {ECO:0000255|HAMAP-Rule:MF_03136}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-dehydroquinate = 3-dehydroshikimate + H2O;
CC Xref=Rhea:RHEA:21096, ChEBI:CHEBI:15377, ChEBI:CHEBI:16630,
CC ChEBI:CHEBI:32364; EC=4.2.1.10; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_03136};
CC -!- PATHWAY: Aromatic compound metabolism; 3,4-dihydroxybenzoate
CC biosynthesis; 3,4-dihydroxybenzoate from 3-dehydroquinate: step 1/2.
CC {ECO:0000255|HAMAP-Rule:MF_03136}.
CC -!- SUBUNIT: Homododecamer. Adopts a ring-like structure, composed of an
CC arrangement of two hexameric rings stacked on top of one another.
CC {ECO:0000255|HAMAP-Rule:MF_03136}.
CC -!- SIMILARITY: Belongs to the type-II 3-dehydroquinase family.
CC {ECO:0000255|HAMAP-Rule:MF_03136}.
