Inhibition of HeLa cell DNA topoisomerase I by ATP and phosphate.
The relaxation activity of DNA topoisomerase I from HeLa cell nuclei is strongly inhibited by a variety of purine nucleotides in the presence but not absence of 1 mM potassium phosphate. For ATP, 3-4 mM causes nearly complete inhibition. The 2'-and 3'-AMP isomer are active as well in the p...
