Dehydro-L-gulonate decarboxylase

The enzyme dehydro- L -gulonate decarboxylase catalyzes the chemical reaction


 * 3-dehydro-L-gulonate $$\rightleftharpoons$$ L-xylulose + CO2

This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is 3-dehydro-L-gulonate carboxy-lyase (L-xylulose-forming). This enzyme participates in pentose and glucuronate interconversions.
