General annotation (Comments)

Function

Plays a central role in chromosome condensation, segregation and cell cycle progression. Functions as a homodimer, which is essential for chromosome partition. Involved in negative DNA supercoiling in vivo, and by this means organize and compact chromosomes. May achieve or facilitate chromosome segregation by condensation DNA from both sides of a centrally located replisome during cell division By similarity. HAMAP-Rule MF_01800

Subunit structure

Homodimerization via its hinge domain. Binds to DNA via its C-terminal region. Interacts, and probably forms a ternary complex, with MukE and MukF via its C-terminal region. The complex formation is stimulated by calcium or magnesium. Interacts with tubulin-related protein FtsZ By similarity.

Subcellular location

Cytoplasmnucleoid By similarity. Note: Restricted to the nucleoid region By similarity. HAMAP-Rule MF_01800

Domain

The hinge domain, which separates the large intramolecular coiled coil regions, allows the homodimerization, forming a V-shaped homodimer By similarity. HAMAP-Rule MF_01800

Sequence similarities

Belongs to the SMC family. MukB subfamily.
