DNA gyrase subunit A in Escherichia coli (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL1858] [GtoPdb: 3217] [UniProtKB: P0AES4] | ||||||||
ChEMBL | Fluorescence Polarisation Assay: In a black, 384-well polystyrene assay plate, 30 microliters/well of 5 nM Escherichia coli DNA gyrase A/B tetramer and 130 micrograms/mL of topological^ relaxed plasmid containing the triplex-forming sequence TTCTTCTTCTTCTTCTTCTTCTTCTTC (SEQ ID NO: 1) in an assay buffer consisting of 35 mM Tris-HCI (pH 7.5), 24 mM KCI, 4 mM MgCI2, 2 mM dithiothreitol, 1.8 mM spermidine, 5% (v/v) glycerol, 200 nM bovine serum albumin, 0.8%dimethylsulfoxide, and 0.3 mM ATP were incubated at ambient temperature for (typically 30 minutes) in the absence or presence of 5 -10 different concentrations of test compound. The supercoiling reactions were quenched by the addition of 10 microliters/well of 40 nM oligodeoxynucleotide probe in 3X triplex-forming buffer consisting of 150 mM NaCI, and 150 mM sodium acetate at pH 3.5. The oligodeoxynucleotide probe was 5'-BODIPY-FL-labeled TTCTTCTTC (SEQ ID NO:2). After 60 minutes, the fluorescence anisotropy of the BODIPY- FL was measured in a Tecan Ultra plate. | B | 6.77 | pIC50 | 169 | nM | IC50 | US-8889671-B2.
