Data class Domain;
Predictors PROSITE; PS51948; COV_NSP12_RDRP
Name Coronavirus Nsp12 RNA-dependent RNA polymerase (RdRp) domain
Function The Nsp12 RNA-dependent RNA polymerase, that includes an RdRp catalytic domain conserved in all RNA viruses, possesses some minimal activity on its own, but the addition of the Nsp7 and Nsp8 cofactors greatly stimulates polymerase activity.
Scope(s) Viruses
Example(s) P0C6Y1 (R1AB_IBVB);
