Some of the general features of the pathway for l-tryptophan biosynthesis in cell cultures of Nicotiana tabccum var. Wisc. 38 have been investigated. The results of both isotope competition and direct-labeling experiments show that shikimic acid, anthranilic acid, indoleglycerol phosphate, and indole can serve as precursors to l-tryptophan in these cells, indicating that, in terms of its biochemical intermediates, the pathway is similar to that described for the bacteria and fungi.
已研究了烟草细胞培养物中天冬氨酸途径合成 l-色氨酸的一些一般特征。同位素竞争和直接标记实验的结果表明,莽草酸、邻氨基苯甲酸、吲哚甘油磷酸和吲哚可以作为这些细胞中 l-色氨酸的前体,表明就其生化中间产物而言,该途径与细菌和真菌中描述的途径相似。
