/ˌkɑrˈbɑksəˌleɪz/,

/ˌkɑrˈbɑksəˌleɪs/

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: carboxyl n., -ase suffix.

Etymology: < carboxyl n. + -ase suffix, after German Carboxylase (C. Neuberg & L. Karczag 1911, in Biochem. Zeitschr. 36 73).

Biochemistry.

Any of various enzymes that bring about a decarboxylation reaction, liberating carbon dioxide typically from a keto acid, or an opposite reaction in which carbon dioxide is fixed.

1934 C. C. Steele Introd. Plant Biochem. vii. xxii. 261 Pyruvic acid is decomposed to acetaldehyde and carbon dioxide by the action of an enzyme termed a carboxylase.

1975 Proc. National Acad. Sci. U.S.A. 72 4308/1 Pyruvate carboxylase..is a biotin-containing enzyme which forms oxalacetate from pyruvate by CO₂ fixation.

2003 Science 28 Mar. 1941/2 Acetyl-coenzyme A carboxylases (ACCs) are critical enzymes in the fatty acid biosynthetic pathway.
