eIF-3 from wheat germ is a large multicomponent factor. It sediments at 15 S and is comprised of ten different polypeptides with an Mr value ranging from 26 000 to 135 000; five out of the ten seem to be present in a 1 : 1 stoichiometric ratio, whereas the others appear to occur approximately in a 0.5 to 1 ratio. The factor is active in a partially purified cell-free system derived from wheat germ and in a mammalian model assay system for the synthesis of methionyl puromycin.
来自小麦胚芽的真核起始因子3（eIF-3）是一种大型多组分因子。它在15 S沉降，由十种不同的多肽组成，其相对分子质量（Mr）值在26 000至135 000之间；十种中的五种似乎以1:1的化学计量比存在，而其他的似乎以大约0.5至1的比例出现。该因子在源自小麦胚芽的部分纯化的无细胞系统以及用于甲硫氨酰嘌呤霉素合成的哺乳动物模型检测系统中具有活性。
