To determine whether loss of … 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.
