In Bacillus subtilis, the tRNA lacks an encoded CCA 3' end. To gain insight into the role of CCAase and RNases in tRNA processing, several mutant strains were generated. Northern blot and RT-PCR results suggest that enzymes other than CCAase can participate in CCA addition at the 3' end of the immature tRNA.
在枯草芽孢杆菌中,tRNA 缺乏编码的 CCA 3'末端。为了深入了解 CCAase 和 RNases 在 tRNA 加工中的作用,生成了几种突变株。Northern blot 和 RT-PCR 结果表明,除了 CCAase 之外的酶也可以参与不成熟 tRNA 3'末端的 CCA 添加。
