SYSTEMATIC NAME
IUBMB Comments
9-cis-10'-apo-beta-carotenal:O2 oxidoreductase (14,15-cleaving, carlactone-forming)
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-beta-carotenal 13,14-cleaving dioxygenase, but 10-fold slower.
