Abstract
Two of the six leucine isoaccepting tRNA species from soybean (Glycine max) cotyledons recognize U-beginning codons, and contain cytokinin moieties in their structure. These same two isoaccepting species have been shown to undergo quantitative changes in their relative amounts upon treatment with N(6)-benzyladenine in vivo. In addition a procedure has been developed for purification of the isoaccepting species of leucine tRNA from soybean cotyledons resulting in isoacceptors of minimum purity, calculated by amino acid acceptance capacity, of from 46 to 78% leucine tRNA.
摘要
大豆（Glycine max）子叶中的六种亮氨酸同功tRNA中有两种能识别以U开头的密码子，并且其结构中含有细胞分裂素部分。已证明，在体内用N（6）-苄基腺嘌呤处理后，这两种同功tRNA的相对含量会发生定量变化。此外，还开发了一种从大豆子叶中纯化亮氨酸tRNA同功tRNA的方法，得到的同功受体的最低纯度（根据氨基酸接受能力计算）为46%至78%的亮氨酸tRNA。
