2-dehydro-3-deoxy-L-arabinonate dehydratase

Class of enzymes 2-dehydro-3-deoxy-L-arabinonate dehydratase 4.2.1.43 37263-10-8 0047449 The enzyme 2-dehydro-3-deoxy-L-arabinonate dehydratase (4.2.1.43) catalyzes the chemical reaction 2-dehydro-3-deoxy-L-arabinonate 2,5-dioxopentanoate + 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 2-dehydro-3-deoxy-L-arabinonate hydro-lyase (2,5-dioxopentanoate-forming). Other names in common use include 2-keto-3-deoxy-L-arabinonate dehydratase, and 2-dehydro-3-deoxy-L-arabinonate hydro-lyase. This enzyme participates in ascorbate and aldarate metabolism.
