double-stranded DNA the helicase separates double-stranded RNA or DNA with a 5'-3' polarity, using the energy of ATP hydrolysis. GST-tagged nsp13 shows much more efficient nucleic acid unwinding than the H6-tagged counterpart. At 0.1 second, more than 50% of the ATP is hydrolyzed hydrolysed by GST-nsp13 compared to less than 5% ATP hydrolysis by H6-nsp13 severe acute respiratory syndrome coronavirus single-stranded DNA
