The bases 1175-1542 (3'-term.) and 94-510 of the E. coli (EC) 16S rRNA are both homologous to the [5S rRNA-tRNA Asn-tRNA(Ser)-tRNA(Glu)-tRNA(Val)-tRNA(Met)] region of the Bacillus subtilis (BSU) trrnD operon, and to the S12 and S7 r-protein-encoding region (S12/S7 region) in the EC str operon. The 2570-2906 (3'-term.) of the EC 23S rRNA is also homologous to the trrnD. These rRNAs had evolved from a str-like pre-mRNA.
大肠杆菌(EC)16S rRNA的1175 - 1542位碱基(3'端)和94 - 510位碱基,与枯草芽孢杆菌(BSU)trrnD操纵子的[5S rRNA - tRNA天冬酰胺 - tRNA(丝氨酸) - tRNA(谷氨酸) - tRNA(缬氨酸) - tRNA(甲硫氨酸)]区域同源,也与EC str操纵子中的S12和S7核糖体蛋白编码区域(S12/S7区域)同源。EC 23S rRNA的2570 - 2906位碱基(3'端)也与trrnD同源。这些rRNA由类似str的前体mRNA进化而来。
