| Accepted name: |
all-trans-10′-apo-β-carotenal 13,14-cleaving dioxygenase |
| Reaction: |
all-trans-10′-apo-β-carotenal + O2 = 13-apo-β-carotenone + (2E,4E,6E)-4-methylocta-2,4,6-trienedial |

| Other name(s): |
CCD8 (gene name); MAX4 (gene name); NCED8 (gene name); all-trans-10′-apo-β-carotenal:O2 oxidoreductase (13,14-cleaving) |
| Systematic name: |
all-trans-10′-apo-β-carotenal:oxygen oxidoreductase (13,14-cleaving) |
| Comments: |
Requires Fe2+. The enzyme from the plant Arabidopsis thaliana also catalyses EC 1.13.11.69, carlactone synthase, 10-fold faster. |
