CC   -!- FUNCTION: Essential cell division protein that coordinates cell
CC       division and chromosome segregation. The N-terminus is involved in
CC       assembly of the cell-division machinery. The C-terminus functions as a
CC       DNA motor that moves dsDNA in an ATP-dependent manner towards the difSL
CC       recombination site, which is located within the replication terminus
CC       region. Required for activation of the XerS recombinase, allowing
CC       activation of chromosome unlinking by recombination (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Homohexamer. Forms a ring that surrounds DNA (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}. Note=Located at the septum. {ECO:0000250}.
CC   -!- DOMAIN: Consists of an N-terminal domain, which is sufficient for the
CC       localization to the septal ring and is required for cell division,
CC       followed by a linker domain, and a C-terminal domain, which forms the
CC       translocation motor involved in chromosome segregation. The C-terminal
CC       domain can be further subdivided into alpha, beta and gamma subdomains.
CC       The alpha and beta subdomains form the DNA pump, and the gamma
CC       subdomain is a regulatory subdomain (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the FtsK/SpoIIIE/SftA family. {ECO:0000305}.
