negatively supercoiled DNA
positively supercoiled DNA
the enzyme catalyzes a ATP-dependent DNA-positive supercoiling reaction of closed DNA plasmids. ATP is required for a correct coordination of DNA cleavage. The enzyme is able to induce positive supercoiling with ATP concentrations of 0.0001 mM. The efficiency of the reaction increases with increasing nucleotide concentrations, with an optimum between 0.1 and 1.0 mM. In the absence of ATP, the enzyme shows weak type I topoisomerase-like DNA relaxation activity. At all temperatures, relaxed and/or positive topoisomers are produced when a certain amount of the negative substrate is still present, thus suggesting that the enzyme is highly processive, i.e. it performs multiple supercoiling cycles before detaching from DNA and attacking a new substrate molecule. In the absence of ATP the enzyme shows weak type I topoisomerase-like DNA relaxation activity
