The enzyme xylono-1,4-lactonase (EC 3.1.1.68) catalyzes the reaction

D-xylono-1,4-lactone + H2O D-xylonate

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is D-xylono-1,4-lactone lactonohydrolase. Other names in common use include xylono-γ-lactonase, and xylonolactonase. This enzyme participates in pentose and glucuronate interconversions.

<small>L</small>-gulonolactone oxidase Enzyme involved in the synthesis of vitamin C

L-Gulonolactone oxidase is an enzyme that produces vitamin C, but is non-functional in Haplorrhini, in some bats, and in guinea pigs. It catalyzes the reaction of L-gulono-1,4-lactone with oxygen to form L-xylo-hex-3-gulonolactone (2-keto-gulono-γ-lactone) and hydrogen peroxide. It uses FAD as a cofactor. The L-xylo-hex-3-gulonolactone then converts to ascorbic acid spontaneously, without enzymatic action.
