General Information | Comment | Organism |
---|---|---|
physiological function | the carotenoid cleavage dioxygenase 8, CCD8, catalyzes a series of reactions and molecular rearrangements for biosynthesis of strigolactones, a class of phytohormones synthesized from carotenoids via carlactone. The complex structure of carlactone is not easily deducible from its precursor 9-cis-beta-apo-10'-carotenal, a cis-configured beta-carotene cleavage product.
