We have isolated 18S RNA from cytoplasmic extracts of Newcastle disease virus-infected Chinese hamster ovary cells and tested its ability to direct protein synthesis in extracts derived from wheat germ. The products of the cell-free reaction directed by this RNA contain polypeptides that comigrate with NP, M,F, and 47K roteins from virions. In addition, the products contain a polypeptide (67K) that migrates on polyacrylamide gels slightly faster than the HN protein from virions. Tryptic peptide analysis of the cell-free products and proteins from virions confirms their identity.
我们从感染新城疫病毒的中国仓鼠卵巢细胞的细胞质提取物中分离出18S RNA,并测试了其在小麦胚芽提取物中指导蛋白质合成的能力。由这种RNA指导的无细胞反应产物包含与病毒粒子中的NP、M、F和47K蛋白迁移率相同的多肽。此外,产物还包含一种多肽(67K),其在聚丙烯酰胺凝胶上的迁移速度比病毒粒子中的HN蛋白略快。对无细胞产物和病毒粒子蛋白进行的胰蛋白酶肽分析证实了它们的同一性。
