| Background | The RdRp of SARS-CoV-2 is composed of a catalytic subunit known as nsp12 as well as two accessory subunits, nsp8 and nsp7. The structure of this RdRp has recently been reported; it is highly similar to the RdRp of SARS-CoV, a zoonotic coronavirus that spread into the human population in 2002. The nsp12 subunit contains an N-terminal nidovirus RdRp-associated nucleotidyltransferase (NiRAN) domain, an interface domain and a C-terminal RdRp domain. The RdRp domain resembles a right hand, comprising the fingers, palm and thumb subdomains that are found in all single-subunit polymerases. Subunits nsp7 and nsp8 bind to the thumb, and an additional copy of nsp8 binds to the fingers domain. Structural information is also available for nsp8–nsp7 complexes. |
