Using RNA from developing cotyledons and leaves of bean two products were synthesizedin vitro, with Mr 31000 and 31500 which are antigenically related to the subunit of phytoferritin (Mr 26500). The relative abundance of the two products is dependent on the type of tissue from which the RNA was derived. Evidence is presented for the assumption that both products are precursors of the phytoferritin subunit. The hypothesis is put forward that different transit sequences direct the phytoferritin subunits to different cell organelles.
利用来自发育中的子叶和豆科植物叶片的 RNA,体外合成了两种产物,它们的分子量分别为 31000 和 31500,与植物铁蛋白亚基(分子量为 26500)具有抗原相关性。这两种产物的相对丰度取决于 RNA 来源的组织类型。有证据表明,这两种产物都是植物铁蛋白亚基的前体。提出了这样的假设,即不同的转运序列将植物铁蛋白亚基导向不同的细胞器。
