car·box·y·lase (kahr-bokґsə-lās) an enzyme that catalyzes the addition of a molecule of carbon dioxide to another compound to form a carboxyl group. The carboxylases include some carboxy-lyases [EC 4.1.1] and those ligases, usually biotinyl-proteins, that cleave ATP to drive the reaction [EC 6.4.1].
