Experimental and computational investigations of Ser10 and Lys13 in the binding and cleavage of DNA substrates by Escherichia coli DNA topoisomerase I
Ser10 and Lys13 found near the active site tyrosine of Escherichia coli DNA topoisomerase I are conserved among the type IA topoisomerases. Site-directed mutagenesis of these two residues to Ala reduced the relaxation and DNA cleavage activity, with a more severe effect from the Lys13 mutation. Chan...
