NSP12 contains a polymerase domain that assumes a structure resembling a cupped 'right hand', similar to other polymerases, containing a fingers domain, a palm domain and a thumb domain. Coronavirus NSP12 also contains a nidovirus-unique N-terminal extension (nidovirus RdRp-associated nucleotidyltransferase (NiRAN) that possesses a kinase-like fold allowing the binding of NSP12 to NSP7 and NSP8. NSP12 possesses some minimal activity on its own, but the addition of the NSP7 and NSP8 co-factors greatly stimulates polymerase activity [1,2,3,4]. This domain represents the N-terminal region of the coronavirus RNA-directed RNA Polymerase, which includes the NiRAN and interface domains [1,4]. The function of the NiRAN domain is not clear and its target is yet unknown, but it has enzymatic activity that is essential for viral propagation. Structure from SARS-CoV-2 revealed that this domain binds ADP-Mg+2, which may constitute a new pocket for anti-viral treatment development [5].

It forms a hexadecameric supercomplex with NSP8 that adopts a hollow cylinder-like structure [2]. The dimensions of the central channel and positive electrostatic properties of the cylinder imply that it confers processivity on RNA-dependent RNA polymerase [2]. NSP7 and NSP8 heterodimers play a role in the stabilisation of NSP12 regions involved in RNA binding and are essential for a highly active NSP12 polymerase complex [3].

It plays a critical role catalysing the unwinding of duplex oligonucleotides into single strands in an NTP-dependent manner. It is a multidomain protein consisting of a N-terminal zinc-binding domain (ZBD), a stalk domain that connects the ZBD with the 1B domain and the helicase domain (that contains two RecA1 and RecA2 domains). ZBD, stalk and 1B domains are unique to nidovirus helicases [1]. NSP13 adopts a triangular pyramid shape in which the two RecA1 and A2 and 1B domains form the triangular base while N-terminal ZBD and stalk domains are arranged at the apex of the pyramid [1,2]. Recently, it has been reported that SARS-CoV-2 NSP13 as an interferon antagonist [3]. This is 1B domain of NSP13 [1], which has a regulatory role modulating the nucleic acid substrate binding [2].

It plays a critical role catalysing the unwinding of duplex oligonucleotides into single strands in an NTP-dependent manner. It In SARS-CoV, it has been shown that NSP12 directly interacts with NSP13 and enhances its helicase activity. It is a multidomain protein consisting of a N-terminal zinc-binding domain (ZBD), a stalk domain that connects the ZBD with the 1B domain and the helicase domain (that contains two RecA1 and RecA2 domains).

Recently, it has been reported that SARS-CoV-2 NSP13 as an interferon antagonist [3]. This is the zinc-binding domain (ZBD) found at the N-terminal of NSP13 which is critically involved in nidovirus replication and transcription, modulating the ATPase/helicase activity in cis [1,2]. It includes conserved cysteines and histidines involved in three zinc-binding sites [4].

Several crystallographic structures of nsp9 have shown that it is composed of seven beta strands and a single alpha helix. Nsp9 proteins have N-finger motifs and highly conserved GXXXG motifs that both play critical roles in dimerisation [2]. The conserved helix-helix dimer interface containing a GXXXG protein-protein interaction motif is biologically relevant to SARS-CoV replication.
