| + | [[http://www.uniprot.org/uniprot/PARE_ECOLI PARE_ECOLI]] Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule. MukB stimulates the relaxation activity of topoisomerase IV and also has a modest effect on decatenation.<ref>PMID:21300644</ref> <ref>PMID:15105144</ref> <ref>PMID:20921377</ref> | ||

| + | == Publication Abstract from PubMed == | ||
| + | The bacterial topoisomerases DNA gyrase (GyrB) and topoisomerase IV (ParE) are essential enzymes that control the topological state of DNA during replication. The high degree of conservation in the ATP-binding pockets of these enzymes make them appealing targets for broad-spectrum inhibitor development. A pyrrolopyrimidine scaffold was identified from a pharmacophore-based fragment screen with optimization potential. Structural characterization of inhibitor complexes conducted using selected GyrB/ParE orthologs aided in the identification of important steric, dynamic and compositional differences in the ATP-binding pockets of the targets, enabling the design of highly potent pyrrolopyrimidine inhibitors with broad enzymatic spectrum and dual targeting activity. | ||
