- | 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.

Function
PARE_FRATH Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA (PubMed:23352267, PubMed:23294697, PubMed:24386374). Performs the decatenation events required during the replication of a circular DNA molecule.[HAMAP-Rule:MF_00938][1] [2] [3]
