Comments
[?]
| FUNCTION | Involved in the third step of the chorismate pathway, which leads to the biosynthesis of aromatic amino acids. Catalyzes the cis- dehydration of 3-dehydroquinate (DHQ) and introduces the first double bond of the aromatic ring to yield 3-dehydroshikimate. |
| CATALYTIC ACTIVITY | Reaction=3-dehydroquinate = 3-dehydroshikimate + H2O; Xref=Rhea:RHEA:21096, ChEBI:CHEBI:15377, ChEBI:CHEBI:16630, ChEBI:CHEBI:32364; EC=4.2.1.10; |
| PATHWAY | Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 3/7. |
| SUBUNIT | Homodimer. |
| SIMILARITY | Belongs to the type-I 3-dehydroquinase family. |
