additional information shorter beta-apocarotenals, i.e. beta-apo-10-carotenal, beta-apo-12'-carotenal, and beta-apo-14'-carotenal, do not show Michaelis-Menten behavior under the conditions tested. No activity with lutein, zeaxanthin, and 9-cis-beta-carotene. Purified recombinant BCO1 cleaves beta-carotene solely at the central 15-15' bond Homo sapiens ?
