Homologous genes for threonine tRNAs with the anticodon CGU have been identified in the region of the proBA operon of Escherichia coli and downstream from the fimbrial subunit gene of Pseudomonas aeruginosa. tRNAs with the anticodon CGU have not previously been identified from either of these bacterial species. Sequence analyses have shown that these genes are similar to other bacterial tRNA genes, and that the predicted structure conforms to the standard cloverleaf model, including retention of all invariant and semi-invariant bases. Analysis of upstream sequences suggests that these genes have associated promoters and are probably expressed in vivo.
在大肠杆菌的proBA操纵子区域以及铜绿假单胞菌菌毛亚基基因下游,已鉴定出具有反密码子CGU的苏氨酸tRNA的同源基因。此前尚未从这两种细菌中鉴定出具有反密码子CGU的tRNA。序列分析表明,这些基因与其他细菌tRNA基因相似,并且预测的结构符合标准的三叶草模型,包括所有不变和半不变碱基的保留。对上游序列的分析表明,这些基因具有相关的启动子,可能在体内表达。
