| Cryo-electron microscopy structure of the SARS-CoV-2 RdRp with non-structural protein 12 (nsp12), nsp8 and nsp7, and more than two turns of RNA template-product duplex, shows active-site cleft of nsp12 binds to the first turn of RNA and mediates RdRp activity and two copies of nsp8 bind to opposite sides of the cleft and position the second turn of RNA. Nsp8 along the exiting RNA, forms positively charged 'sliding poles' which affect the processivity of RdRp. | The active site of nsp12 consists of five conserved motif AE, of which the residues (D760 and D761) of motif C binds to the RNA 3 end and plays a crucial role in RNA synthesis. K58 is located in the nsp8 extension and plays an important role in interaction with RNA. ✍ | 32438371 (Nature)
