A low-resolution three-gate structure of topoisomerase IV from Streptococcus pneumoniae in space group H32

Template:ABSTRACT PUBMED 23965305

Function

[PARC_STRPN] Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule.^{[1] [2]} [PARE_STRPN] Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule.^{[3] [4]}
