Apo beta carotenoid 14',13' dioxygenase

Apo-beta-carotenoid-14',13'-dioxygenase (EC 1.13.12.12) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are 8'-apo-beta-carotenol and oxygen, whereas its two products are 14'-apo-beta-carotenal and water.

This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O₂ as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O with incorporation of one atom of oxygen (internal monooxygenases o internal mixed-function oxidases). The systematic name of this enzyme class is 8'-apo-beta-carotenol:O2 oxidoreductase.
