Function
function
Catalyzes the conversion of 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) to dehydroquinate (DHQ).
Catalytic activity
- 7-phospho-2-dehydro-3-deoxy-D-arabino-heptonate = 3-dehydroquinate + phosphate
Cofactor
Protein has several cofactor binding sites:
Zn2+ (UniProtKB | Rhea| CHEBI:29105 )
Note: Binds 1 divalent metal cation per subunit. Can use either Co2+ or Zn2+.
Pathway
Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 2/7.
