WebFeb 21, 2006 · A cyp97a3-null allele, lut5-1, causes an accumulation of α-carotene at a level equivalent to β-carotene in wild type, which is stably incorporated into photosystems, and a 35% reduction in β-carotene … Webcan partially compensate for the loss of CYP97A3 activity. From these data, we propose a model for the preferred pathway for lutein synthesis in plants: ring cyclizations to form a-carotene, p-ring hydroxylation of a-carotene by CYP97A3 to produce zeinox-anthin, followed by e-ring hydroxylation of zeinoxanthin by CYP97C1 to produce lutein.
