|Zeaxanthin + O(2) <=> (3R)-11-cis-3-hydroxyretinal + (3R)-all-trans-3-hydroxyretinal|
- The enzyme, characterized from the moth Galleria mellonella and the
fruit fly Drosophila melanogaster, is involved in the synthesis of
retinal from dietary caroteoids in insects.
- The enzyme accepts different all-trans carotenoids, including beta-
carotene, alpha-carotene and lutein, and catalyzes the symmetrical
cleavage of the carotenoid and the simultaneous isomerization of only
one of the products to a cis configuration.
- When the substrate is hydroxylated only in one side (as in
cryptoxanthin), the enzyme preferentially isomerizes the hydroxylated
part of the molecule.
- Formerly EC 188.8.131.52.
