Carlactone synthase (
EC
1.13.11.69, CCD8 (gene), MAX4 (gene), NCED8 (gene)) is an
enzyme with
systematic name 9-cis-10'-apo-beta-carotenal:O2 oxidoreductase (14,15-cleaving, carlactone-forming).
[1]
[2]
[3] This enzyme
catalyses the following
chemical reaction
- 9-cis-10'-apo-beta-carotenal + 2 O2
carlactone + (2E,4E,6E)-7-hydroxy-4-methylhepta-2,4,6-trienal
Carlactone synthase contains Fe2+.
