Galactarate dehydratase

The enzyme galactarate dehydratase catalyzes the chemical reaction


 * D -galactarate $$\rightleftharpoons$$ 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 -galactarate hydro-lyase (5-dehydro-4-deoxy- D -glucarate-forming). This enzyme is also called  D -galactarate hydro-lyase. This enzyme participates in ascorbate and aldarate metabolism.
