Analysis of the nucleoside composition of five lysine tRNAs from lupin seeds has shown their general similarity to other eukaryotic lysine tRNAs, except that lupin lysine tRNAs do not contain either t6A, Tm, or thioderivatives of uridine. It is assumed that each of the lupin tRNALys is coded for by a separate gene. The acceptor activity of the analysed tRNAs ranged from about 1200 (tRNA3Lys, tRNA4Lys, tRNA5Lys) to 1470 (tRNA2Lys) pmoles of lysine per one A260 unit of tRNA.
对羽扇豆种子中五种赖氨酸tRNA的核苷组成分析表明，它们与其他真核生物赖氨酸tRNA总体相似，只是羽扇豆赖氨酸tRNA既不含有N6-甲基腺嘌呤（t6A）、胸苷（Tm），也不含有尿苷的硫代衍生物。据推测，羽扇豆的每种赖氨酸tRNA都是由一个单独的基因编码的。所分析的tRNA的接受活性范围为每一个A260单位的tRNA约1200（tRNA3Lys、tRNA4Lys、tRNA5Lys）至1470（tRNA2Lys）皮摩尔赖氨酸。
