| Function | Nonheme diiron monooxygenase involved in the biosynthesis of xanthophylls. Specific for beta-ring hydroxylations of beta-carotene. Has also a low activity toward the beta- and epsilon-rings of alpha-carotene. No activity with acyclic carotenoids such as lycopene and neurosporene. Uses ferredoxin as an electron donor (Probable). {ECO:0000305|PubMed:11587509, ECO:0000305|PubMed:12782726, ECO:0000305|PubMed:16890225, ECO:0000305|PubMed:19147649}. |
