In [[enzymology]], a '''L-arabinonolactonase''' ({{EC number|3.1.1.15}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:L-arabinono-1,4-lactone + H<sub>2</sub>O <math>\rightleftharpoons</math> L-arabinonate

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[L-arabinono-1,4-lactone]] and [[water|H<sub>2</sub>O]], whereas its [[product (chemistry)|product]] is [[L-arabinonate]].

This enzyme belongs to the family of [[hydrolase]]s, specifically those acting on carboxylic [[ester]] bonds.  The systematic name of this enzyme class is '''L-arabinono-1,4-lactone lactonohydrolase'''. This enzyme participates in [[ascorbate and aldarate metabolism]].
