9-cis-beta-carotene 9',10'-cleaving dioxygenase (EC 1.13.11.68, CCD7 (gene), MAX3 (gene), NCED7 (gene)) is an enzyme with systematic name 9-cis-beta-carotene:O₂ oxidoreductase (9',10'-cleaving). This enzyme catalyses the following chemical reaction

9-cis-beta-carotene + O₂ ${\displaystyle \rightleftharpoons }$ 9-cis-10'-apo-beta-carotenal + beta-ionone

9-cis-beta-carotene 9',10'-cleaving dioxygenase contains Fe.
