Dihydroxyfumarate decarboxylase

In enzymology, a dihydroxyfumarate decarboxylase is an enzyme that catalyzes the chemical reaction


 * dihydroxyfumarate $$\rightleftharpoons$$ tartronate semialdehyde + CO2

Hence, this enzyme has one substrate, dihydroxyfumarate, and two products, tartronate semialdehyde and 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 dihydroxyfumarate carboxy-lyase (tartronate-semialdehyde-forming). This enzyme is also called dihydroxyfumarate carboxy-lyase. This enzyme participates in glyoxylate and dicarboxylate metabolism.
