The nucleotide sequence of a tobacco chloroplast 23-S rRNA gene, including the spacer between it and the 4.5-S rRNA gene, has been determined. The 23-S rRNA coding region is 2804-base-pairs long. A comparison with the 23-S rRNA sequence of Escherichia coli reveals strong homology and further shows a similarity between the chloroplast 4.5-S rRNA and the 3'-terminal region of E. coli 23-S rRNA. However, the 101-base-pair spacer sequence between the 23-S and 4.5-S rRNA genes has little homology with E. coli 23-S rRNA.
已确定烟草叶绿体23 - S rRNA基因的核苷酸序列,包括它与4.5 - S rRNA基因之间的间隔区。23 - S rRNA编码区长度为2804个碱基对。与大肠杆菌的23 - S rRNA序列比较显示出很强的同源性,并且进一步表明叶绿体4.5 - S rRNA与大肠杆菌23 - S rRNA的3'末端区域相似。然而,23 - S和4.5 - S rRNA基因之间101个碱基对的间隔序列与大肠杆菌23 - S rRNA几乎没有同源性。
