Sulfopyruvate decarboxylase

In enzymology, a sulfopyruvate decarboxylase (EC 4.1.1.79) is an enzyme that catalyzes the chemical reaction

Hence, this enzyme has one substrate, 3-sulfopyruvate, and two products, 2-sulfoacetaldehyde 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 3-sulfopyruvate carboxy-lyase (2-sulfoacetaldehyde-forming). This enzyme is also called sulfopyruvate carboxy-lyase.
