Comments [?]

Function Is involved in the catabolism of quinate. Allows the utilization of quinate as carbon source via the beta-ketoadipate pathway.
Catalytic activity RHEA:21096: 3-dehydroquinate = 3-dehydroshikimate + H2O
EC 4.2.1.10
Pathway Aromatic compound metabolism; 3,4-dihydroxybenzoate biosynthesis; 3,4-dihydroxybenzoate from 3-dehydroquinate: step 1/2.
Subunit Homododecamer. Adopts a ring-like structure, composed of an arrangement of two hexameric rings stacked on top of one another.
Similarity Belongs to the type-II 3-dehydroquinase family.
