In [[enzymology]], a '''L-arabinonate dehydratase''' ({{EC number|4.2.1.25}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]<br />
<br />
:L-arabinonate <math>\rightleftharpoons</math> 2-dehydro-3-deoxy-L-arabinonate + H<sub>2</sub>O<br />
<br />
Hence, this enzyme has one [[substrate (biochemistry)|substrate]], [[L-arabinonate]], and two [[product (chemistry)|products]], [[2-dehydro-3-deoxy-L-arabinonate]] and [[water|H<sub>2</sub>O]].<br />
<br />
This enzyme belongs to the family of [[lyase]]s, 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]]. <br />
