CCD

Protein

Carotenoid 9,10(9',10')-cleavage dioxygenase

Organism

Crocus sativus

Length

546 amino acids

Function

Cleaves a variety of carotenoids symmetrically at both the 9-10 and 9'-10' double bonds. Catalyzes the formation of 4,9-dimethyldodeca-2,4,6,8,10-pentaene-1,12-dialdehyde and probably hydroxydihydro-beta-ionone from zeaxanthin.

Similarity

Belongs to the carotenoid oxygenase family.
