===Crystal structure of apocarotenoid oxygenase in the presence of Triton X-100===


==Function==
==Crystal structure of apocarotenoid oxygenase in the presence of Triton X-100==
[[http://www.uniprot.org/uniprot/ACOX_SYNY3 ACOX_SYNY3]] Cleaves a number of carotenals and carotenols in the all-trans configuration at the 15-15' double bond producing retinal or retinol, respectively. Also shows activity toward lycopenals and the corresponding alcohols. Does not cleave beta-carotene or lycopene.
