Tartrate decarboxylase

In enzymology, a tartrate decarboxylase (EC 4.1.1.73) is an enzyme that catalyzes the chemical reaction

Hence, this enzyme has one substrate, (R,R)-tartrate, and two products, D-glycerate 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 (R,R)-tartrate carboxy-lyase (D-glycerate-forming). This enzyme is also called (R,R)-tartrate carboxy-lyase.
