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 dif
CC       recombination site, which is located within the replication terminus
CC       region. Translocation stops specifically at Xer-dif sites, where FtsK
CC       interacts with the Xer recombinase, allowing activation of chromosome
CC       unlinking by recombination. FtsK orienting polar sequences (KOPS) guide
CC       the direction of DNA translocation. FtsK can remove proteins from DNA
CC       as it translocates, but translocation stops specifically at XerCD-dif
CC       site, thereby preventing removal of XerC and XerD from dif (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homohexamer. Forms a ring that surrounds DNA (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Single-pass
CC       membrane protein {ECO:0000250}. Note=Located at the septum.
CC       {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 multimerise to produce a hexameric ring,
CC       contain the nucleotide binding motif and form the DNA pump. The gamma
CC       subdomain is a regulatory subdomain that controls translocation of DNA
CC       by recognition of KOPS motifs and interacts with XerD recombinase (By
CC       similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the FtsK/SpoIIIE/SftA family. {ECO:0000305}.
