We report a method for the in vitro study of peptide chain termination in mammals. A proteinaceous release factor has been isolated from rabbit reticulocyte extracts. This factor and a polyribonucleotide template containing the bases U and A stimulate the release of N-formylmethionine from mammalian [N-formylmethionyl-tRNA(f).ribosome] intermediates. Our studies suggest that UAA is a terminator codon for mammalian cells.
我们报道了一种用于哺乳动物肽链终止体外研究的方法。已从兔网织红细胞提取物中分离出一种蛋白质释放因子。该因子和一个含有碱基U和A的多聚核糖核苷酸模板可刺激N-甲酰甲硫氨酸从哺乳动物的[N-甲酰甲硫氨酰-tRNA(f).核糖体]中间体中释放出来。我们的研究表明UAA是哺乳动物细胞的终止密码子。
