3-dehydroquinate Dehydratase

In enzymology, a 3-dehydroquinate dehydratase (EC 4.2.1.10) is an enzyme that catalyzes the chemical reaction

3-dehydroquinate 3-dehydroshikimate + H₂O

Hence, this enzyme has one substrate, 3-dehydroquinate, and two products, 3-dehydroshikimate and H₂O.

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. This enzyme participates in phenylalanine, tyrosine and tryptophan biosynthesis.
