Figure 6From: The DNA relaxation activity and covalent complex accumulation of Mycobacterium tuberculosis topoisomerase I can be assayed in Escherichia coli: application for identification of potential FRET-dye labeling sitesRelaxation activity of CPM labeled MtTOP1-K524C mutant. Serial dilutions of unlabeled MtTOP1-K524C mutant and CPM labeled MtTOP1-K524C mutant proteins were assayed for relaxation of supercoiled plasmid DNA.Back to article page
