FtsK has extensive sequence similarity to wide variety of proteins from prokaryotes and plasmids [1], termed the FtsK/SpoIIIE family. This domain contains a putative ATP binding P-loop motif. It is found in the FtsK cell division protein from E. coli Swiss:P46889 and the stage III sporulation protein E SpoIIIE Swiss:P21458 which has roles in regulation of prespore specific gene expression in B. subtilis. A mutation in FtsK causes a temperature sensitive block in cell division and it is involved in peptidoglycan synthesis or modification [1]. The SpoIIIE protein is implicated in intercellular chromosomal DNA transfer [1].	Domain

FtsK is a DNA translocase that coordinates chromosome segregation and cell division in bacteria [1]. In addition to its role as activator of XerCD site-specific recombination, FtsK can translocate double-stranded DNA (dsDNA) rapidly and directionally and reverse direction [1]. FtsK can be split into three domains called alpha (this entry), beta and gamma. The alpha and beta domains contain the core ATPase machinery of the DNA translocase [1].	Domain
