The enzyme glucarate dehydratase (EC 4.2.1.40) catalyzes the chemical reaction

D-glucarate 5-dehydro-4-deoxy-D-glucarate + H2O

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is D-glucarate hydro-lyase (5-dehydro-4-deoxy-D-glucarate-forming). Other names in common use include D-glucarate dehydratase, and D-glucarate hydro-lyase. This enzyme participates in ascorbate and aldarate metabolism.

Structural studies

[edit]
