Phosphonopyruvate decarboxylase

In enzymology, a phosphonopyruvate decarboxylase (EC number|4.1.1.82) is an enzyme that catalyzes the chemical reaction

:3-phosphonopyruvate $ightleftharpoons$ 2-phosphonoacetaldehyde + CO₂

Hence, this enzyme has one substrate, 3-phosphonopyruvate, and two products, 2-phosphonoacetaldehyde 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-phosphonopyruvate carboxy-lyase (2-phosphonoacetaldehyde-forming). This enzyme is also called 3-phosphonopyruvate carboxy-lyase. This enzyme participates in aminophosphonate metabolism.
