Enhanced duplex RNA unwinding by the cooperative translocation of helicase nsP13 under adequate ATP concentrations. (A) Gel retardation assay of nsP13 and duplex RNA substrates. The unwinding of 30U/25D RNA with 0.5 μM and 2 μM helicase nsP13. The unwinding reaction was performed with 8 mM ATP and 5 nM substrate at 37 °C. The unwinding products were resolved by non-denaturing 15% PAGE. (B) The amplitudes were as follows: 0.5 μM helicase nsP13 (●) = 0.68 ± 0.01 and 2 μM helicase nsP13 () = 0.96 ± 0.005.
