In enzymology, a 4-carboxymethyl-4-methylbutenolide mutase (EC 5.4.99.14) is an enzyme that catalyzes the chemical reaction

4-carboxymethyl-4-methylbut-2-en-1,4-olide 4-carboxymethyl-3-methylbut-2-en-1,4-olide

Hence, this enzyme has one substrate, 4-carboxymethyl-4-methylbut-2-en-1,4-olide, and one product, 4-carboxymethyl-3-methylbut-2-en-1,4-olide.

This enzyme belongs to the family of isomerases, specifically those intramolecular transferases transferring other groups. The systematic name of this enzyme class is 4-carboxymethyl-4-methylbut-2-en-1,4-olide methylmutase. Other names in common use include 4-methyl-2-enelactone isomerase, 4-methylmuconolactone methylisomerase, and 4-methyl-3-enelactone methyl isomerase.

Carotenoids are yellow, orange, and red organic pigments that are produced by plants and algae, as well as several bacteria, archaea, and fungi. Carotenoids give the characteristic color to pumpkins, carrots, parsnips, corn, tomatoes, canaries, flamingos, salmon, lobster, shrimp, and daffodils. Over 1,100 identified carotenoids can be further categorized into two classes – xanthophylls and carotenes.

The Controlled Drugs and Substances Act is Canada's federal drug control statute. Passed in 1996 under Prime Minister Jean Chrétien's government, it repeals the Narcotic Control Act and Parts III and IV of the Food and Drugs Act, and establishes eight Schedules of controlled substances and two Classes of precursors. It provides that "The Governor in Council may, by order, amend any of Schedules I to VIII by adding to them or deleting from them any item or portion of an item, where the Governor in Council deems the amendment to be necessary in the public interest."
