The enzyme 2-dehydro-3-deoxy-L-arabinonate dehydratase (EC 4.2.1.43) catalyzes the chemical reaction
- 2-dehydro-3-deoxy-L-arabinonate [math]\displaystyle{ \rightleftharpoons }[/math] 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.
