nsp13, which functions as the viral helicase, is as a part of the SARS coronavirus 2 (SARS-CoV-2) replication-transcription complex (RTC). Two molecules of SARS-CoV-2 nsp13 are found in the RTC complex. N-terminal domains of each nsp13 interact with N-terminal extensions of each copy of nsp8, while nsp13 molecule interacts with the thumb region of nsp12, the viral RNA-dependent RNA polymerase. One nsp13 molecule of SARS-CoV-2 is tightly bound to the RTC, while the other nsp13 molecule is dissociable (Chen et al. 2020). In SARS-CoV-1, nsp13 has been reported to directly interact with nsp12, and nsp12 was shown to increase the helicase activity of nsp13 (von Brunn et al. 2007, Adedeji et al. 2012, Jia et al. 2019).
