SYSTEMATIC NAME
IUBMB Comments
8'-apo-beta-carotenol:O2 oxidoreductase (14',13'-cleaving)
A thiol-dependent enzyme isolated from rat and rabbit. Unlike EC 1.13.11.63, beta-carotene-15,15'-dioxygenase, it is not active towards beta-carotene. The secondary product has not been characterized, but may be (3E,5E)-7-hydroxy-6-methylhepta-3,5-dien-2-one.
