DNA gyrase B subunit, C-terminal (IPR002288)

Short name: DNA_gyrase_B_C

Overlapping homologous superfamilies

Domain relationships



This entry represents the C-terminal of the DNA gyrase B. The N terminus of eukaryotic and prokaryotic DNA topoisomerase II are similar, but they have a different C terminus. The N-terminal of the DNA gyrase B protein is thought to catalyse the ATP-dependent super-coiling of DNA. The C-terminal end supports the complexation with the DNA gyrase A protein and the ATP-independent relaxation. This entry also contains Topoisomerase IV, which is a bacterial enzyme that is closely related to DNA gyrase [PMID: 7770916, PMID: 8538787].
