The substrate consisted of 12 bp adjacent to 12 nucleotides of single-stranded DNA. Dda (4 nM) was incubated with substrate (16 nM) in buffer, and the unwinding reaction was initiated by the addition of ATP (5 mM) and Mg 2+ …
WebThe results show that substantial DNA unwinding of the 30-bp forked DNA occurred during the preloading reaction containing ATPγS. In contrast, use of AMP-PNP preloads CMG onto forked DNA without unwinding, and provides a burst of unwinding upon adding ATP that equals the extent of unwinding using ATPγS in the preloading reaction prior to addition of … WebApr 12, 2002 · The unwinding reactions are carried out with 0.5 μg of His tag p68 in 20 μl at 37 °C for 30 min.
