SARS-CoV-2 is the causative agent of worldwide pandemic disease coronavirus disease 19. SARS-CoV-2 bears positive sense RNA genome that has organized and complex pattern of replication/transcription process including the generation of subgenomic RNAs. Transcription regulatory sequences have important role in the pausing of replication/transcription and generation of subgenomic RNAs.
In the present bioinformatics analysis, a consensus secondary structure was identified among negative sense subgenomic RNAs of SARS-CoV-2. This consensus region is present at the adjacent of initiation codon.
This study proposed that consensus structured domain could involve in mediating the long pausing of replication/transcription complex and responsible for subgenomic RNA production.

严重急性呼吸综合征冠状病毒2(SARS-CoV-2)是全球大流行疾病冠状病毒病19的病原体。SARS-CoV-2携带正链RNA基因组,其复制/转录过程具有有组织且复杂的模式,包括亚基因组RNA的产生。转录调控序列在复制/转录的暂停以及亚基因组RNA的产生中起重要作用。
在本生物信息学分析中,在SARS-CoV-2的负链亚基因组RNA中鉴定出一个共有二级结构。该共有区域存在于起始密码子附近。
本研究提出,共有结构域可能参与介导复制/转录复合体的长时间暂停,并负责亚基因组RNA的产生。
