In enzymology, an apo-beta-carotenoid-14',13'-dioxygenase is an enzyme that catalyzes the chemical reaction

8'-apo-beta-carotenol + O2 rightleftharpoons 14'-apo-beta-carotenal + H2O

Thus, the two substrates of this enzyme are 8'-apo-beta-carotenol and O2, whereas its two products are 14'-apo-beta-carotenal and H2O.

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.
