-
enzyme CCD7 cleaves different 9-cis-carotenoids, yielding hydroxylated 9-cis-apo-10'-carotenals that may lead to hydroxylated carlactones, but show highest affinity for 9-cis-beta-carotene. The enzyme has a higher affinity to 9-cis-beta-carotene than to 9-cis-zeaxanthin, but converts the latter with higher rate. No detectable conversion of 9-cis-violaxanthin, all-trans-lutein, -zeaxanthin or -cryptoxanthin

enzyme substrate specificity, dynamic modeling, overview. No activity with the tri-cis-configured PDS or ZDS intermediates and products, i.e. 9,15-di-cis-phytofluene, 9,15,9'-tri-cis-zeta-carotene, 7,9,9'-tri-cis-neurosporene, and 7,9,9',7-tetra-cis-lycopene, as well as with non-canonical isomers of phytofluene (9-cis, 15-cis, all-trans). 9-cis-Lycopene is a poor substrate, and all-trans-lycopene is no substrate. AtCCD7 shows specificity for cleavage of the trans-configured C9-C10 double bond

recombinant ZmCCD7 is able to efficiently catalyze metabolism of linear and cyclic carotenoids in Escherichia coli, and generates bionone by cleaving beta-carotene at the 9,10 (9',10') position. The recombinant enzyme in Escherichia coli catalyzes convertion of individual carotenoids including phytoene, lycopene, delta-carotene, ecarotene, beta-carotene, and zeaxanthin
