In enzymology an arabinonate dehydratase (EC 4.2.1.5) is an enzyme that catalyzes the chemical reactionD-arabinonate 2-dehydro-3-deoxy-D-arabinonate + H2OHence this enzyme has one substrate D-arabinonate and two products 2-dehydro-3-deoxy-D-arabinonate and 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-arabinonate hydro-lyase (2-dehydro-3-deoxy-D-arabinonate-forming).
