Abstract

In chloroplasts, all 61 sense codons are found in chloroplast (cp) DNA sequences coding for proteins. However among the sequenced cp tRNAs or tRNA genes, tRNAs with anticodons complementary to codons CUU/C (Leu), CCU/C (Pro), GCU/C (Ala) and CGC/A/G (Arg) [or CGC/A (Arg) in Marchantia] have not been found. In this paper we show that cp tRNA(Ala)(UGC) cp tRNA(Pro)(UGG) and cp tRNA(Arg)(ICG) are able to decode the corresponding four-codon family. In the case of leucine codons CUU/C, we show that 'U:U and U:C wobble' mechanisms can operate to allow the reading of these codons by cp tRNA(Leu)(UAm7G).

摘要

在叶绿体中，编码蛋白质的叶绿体（cp）DNA序列中存在所有61种有义密码子。然而，在已测序的cp tRNA或tRNA基因中，尚未发现其反密码子与密码子CUU/C（亮氨酸）、CCU/C（脯氨酸）、GCU/C（丙氨酸）和CGC/A/G（精氨酸）[在地钱中为CGC/A（精氨酸）]互补的tRNA。在本文中，我们表明cp tRNA（Ala）（UGC）、cp tRNA（Pro）（UGG）和cp tRNA（Arg）（ICG）能够解码相应的四密码子家族。对于亮氨酸密码子CUU/C，我们表明“U:U和U:C摆动”机制可以发挥作用，使cp tRNA（Leu）（UAm7G）能够读取这些密码子。
