General annotation (Comments)

Function

Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule By similarity. HAMAP-Rule MF_00938

Catalytic activity

ATP-dependent breakage, passage and rejoining of double-stranded DNA. HAMAP-Rule MF_00938

Cofactor

Magnesium. Binds two Mg2+ per subunit. The magnesium ions form salt bridges with both the protein and the DNA. Can also accept other divalent metal cations, such as Mn2+ and Ca2+ By similarity.

Subunit structure

Heterotetramer composed of ParC and ParE By similarity. HAMAP-Rule MF_00938

Sequence similarities

Belongs to the type II topoisomerase family. ParE type 1 subfamily.

Contains 1 Toprim domain.
