| Accepted name: |
9-cis-β-carotene 9′,10′-cleaving dioxygenase |
| Reaction: |
9-cis-β-carotene + O2 = 9-cis-10′-apo-β-carotenal + β-ionone |

| Glossary: |
β-ionone = (3E)-4-(2,6,6-trimethylcyclohex-1-en-1-yl)but-3-en-2-one |
| Other name(s): |
CCD7 (gene name); MAX3 (gene name); NCED7 (gene name) |
| Systematic name: |
9-cis-β-carotene:oxygen oxidoreductase (9′,10′-cleaving) |
| Comments: |
Requires Fe2+. The enzyme participates in a pathway leading to biosynthesis of strigolactones, plant hormones involved in promotion of symbiotic associations known as arbuscular mycorrhiza. |
