Figure 5
Detailed views of the active sites of topoisomerase IV from S. pneumoniae and K. pneumoniae with quinolone molecules bound. The magnesium ions and their coordinating amino acids are shown in purple. The drug molecules and residues known to lead to drug resistance upon mutation are in red. The active-site tyrosine and arginine are in orange. The DNA is shown in silver/cyan. The ParC and ParE backbones are shown in blue and yellow, respectively.
