this suggests that atp hydrolysis fuels continuous translocation of helicase i on circular single-stranded dna while on linear single stranded dna the enzyme translocates to the end of the dna molecule where it must slowly dissociate from the substrate molecule and/or slowly associate with a new substrate molecule , thus resulting in a very low rate of atp hydrolysis .
