ATP + H2O | RECQ5 unwinds duplex DNA with a 3'-5' polarity. Unwinding of longer partial duplex DNA substrates requires a higher protein concentration than does unwinding of the 20bp partial duplex substrate. The unwinding reaction catalyzed by RECQ5 requires a nucleoside 5'-phosphate. dATP is most effective. RECQ5 hydrolyzes dATP more rapidly than ATP regardless of the presence of ssDNA. Both ssDNA cofactors, M13mp18 ssDNA and poly(dT) strongly stimulate the dATPase activity of the protein | Drosophila melanogaster | ADP + phosphate | - |

CTP + H2O | RECQ5 unwinds duplex DNA with a 3'-5' polarity. The unwinding reaction catalyzed RECQ5 requires a nucleoside 5'-phosphate. dATP is most effective. ATP supports helicase reaction with 10% of the efficiency obtained with dATP | Drosophila melanogaster | CDP + phosphate | - |
