Apo-beta-carotenoid-14',13'-dioxygenase (EC 1.13.11.67 is an enzyme that catalyzes the chemical reaction

8'-apo-beta-carotenol + O2 14'-apo-beta-carotenal + uncharacterized product

Thus, the two substrates of this enzyme are 8'-apo-beta-carotenol and oxygen, whereas its two products are 14'-apo-beta-carotenal and an uncharacterized product that may be (3E,5E)-7-hydroxy-6-methylhepta-3,5-dien-2-one.

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.

An oxygenase is any enzyme that oxidizes a substrate by transferring the oxygen from molecular oxygen O2 (as in air) to it. The oxygenases form a class of oxidoreductases; their EC number is EC 1.13 or EC 1.14.
