Structural basis for plant lutein biosynthesis from α-carotene
WebFeb 1, 2013 · New carotenoids from the thermophilic green sulfur bacterium Chlorobium tepidum: 1',2'-dihydro-gamma-carotene, 1',2'-dihydrochlorobactene, and OH-chlorobactene glucoside ester, and the carotenoid composition of different strains. 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 … kids and kitchen

WebIn fact, overexpression of CYP97A3 in orange carrots restored leaf carotenoid patterns almost to those found in white-rooted cultivars and strongly reduced α-carotene levels in the roots. Unexpectedly, this was accompanied by a 30 to 50% reduction in total root carotenoids and correlated with reduced PSY protein levels while PSY expression was ... WebIn our hands, the crystals of unliganded CYP97A3 diffracted to 2.40 Å resolution. The structure of CYP97A3 was determined using the structure of CYP102A1 (P450 BM3) from Bacillus megaterium (PDB: 4KF2) ( Butler et al., 2013) as the search model by molecular replacement with Phaser ( McCoy et al., 2007 ). 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. is metronidazole safe for puppies
