RdRP assay using a hairpin RNA substrate. (A) Schematic structure of the hairpin RNA. (B) Time-dependent incubation of NSP7, NSP8 and/or NSP12 with RNA template. (C) Time-dependent incubation of NSP7, NSP8 and NSP12 with RNA template, with NSP7 or NSP8 mutated at interface I. TM refers to NSP7 F49A/M52A/L56A triple mutation. (D) Time-dependent incubation of NSP7, NSP8 and NSP12 with RNA template, with NSP7 or NSP8 mutated at interface II. (E) Time-dependent incubation of NSP7, NSP8 and NSP12 with RNA template, with NSP8 mutated at the N-terminal domain.
