L-arabinonate dehydratase

The enzyme  L -arabinonate dehydratase catalyzes the chemical reaction


 * L -arabinonate $$\rightleftharpoons$$ 2-dehydro-3-deoxy- L -arabinonate + 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  L -arabinonate hydro-lyase (2-dehydro-3-deoxy- L -arabinonate-forming). Other names in common use include  L -arabonate dehydrase,  L -arabonate dehydratase, and  L -arabinonate hydro-lyase. This enzyme participates in ascorbate and aldarate metabolism.
