Carnitine decarboxylase

In enzymology, a carnitine decarboxylase (EC 4.1.1.42) is an enzyme that catalyzes the chemical reaction

Hence, this enzyme has one substrate, carnitine, and two products, 2-methylcholine 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 carnitine carboxy-lyase (2-methylcholine-forming). This enzyme is also called carnitine carboxy-lyase. It employs one cofactor, ATP.
