摘要
腹腔注射[1-14C]葡萄糖胺后，以不同的时间间隔测定小鼠肝脏亚细胞组分的比活性。微粒体微粒的脱氧胆碱可溶性部分是最活跃的。在体内[14C]氨基葡萄糖通过尿苷二磷酸- n -乙酰氨基葡萄糖掺入微粒体片段的过程中，高速上清部分分离的可溶性核糖核酸不被标记。核糖体中的可溶性核糖核酸也未标记。在体外将[14C]葡萄糖胺掺入核糖核酸的尝试也没有成功。讨论了碳水化合物加成多肽链的可能机理。
Soluble ribonucleic acid and glycoprotein biosynthesis in the mouse liver
The specific activity of subcellular fractions of liver was determined at varying intervals after the intraperitoneal injection of [1-14C]glucosamine in mice. The deoxycholate-soluble portion of microsomal particulates was the most active. During the course of [14C]glucosamine incorporation into microsomal fraction in vivo, by way of uridine diphosphate-N-acetylglucosamine, the soluble ribonucleic acids isolated from the high-speed supernatant fraction were not labeled. Soluble ribonucleic acids from ribosomes were unlabeled also. Attempts to incorporate [14C]glucosamine into ribonucleic acids in vitro were also unsuccessful. A possible mechanism of carbohydrate addition to polypeptide chains is discussed.
