10S RNA has been isolated from the postribosomal supernatant of rabbit reticulocyte lysate. This RNA is associated with protein in a ribonucleoprotein particle that sediments at approximately 20S. The 10S RNA extracted from this particle codes predominantly for alpha globin chains when it is translated by a mouse ascites cell-free extract. The product of the cell-free synthesis has been characterized by column chromatography and electrophoresis of the tryptic peptides. About 20% of the total alpha chain mRNA is present in the postribosomal supernatant, whereas beta chain mRNA is almost exclusively associated with polyribosomes.
10S RNA已从兔网织红细胞裂解物的核糖体后上清液中分离出来。这种RNA与一种沉降系数约为20S的核糖核蛋白颗粒中的蛋白质相关联。从该颗粒中提取的10S RNA在由小鼠腹水无细胞提取物进行翻译时,主要编码α珠蛋白链。无细胞合成产物已通过胰蛋白酶肽段的柱色谱和电泳进行了表征。约20%的α链mRNA存在于核糖体后上清液中,而β链mRNA几乎完全与多核糖体相关联。
