IntEnz Enzyme Nomenclature
EC 1.13.11.69

Names

Accepted name:
carlactone synthase
Other names:
CCD8 (gene name)
MAX4 (gene name)
NCED8 (gene name)
Systematic name:
9-cis-10'-apo-β-carotenal:oxygen oxidoreductase (14,15-cleaving, carlactone-forming)

Reaction

Cofactor

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. Also catalyses EC 1.13.11.70, all-trans-10'-apo-β-carotenal 13,14-cleaving dioxygenase, but 10-fold slower.
