<p>The FtsK/SpoIIIE domain is found extensively in a wide variety of proteins from prokaryotes and plasmids [<cite idref="PUB00002282"/>] some of which contain up to three copies.The domain contains a putative ATP binding P-loop motif. A mutation in FtsK causes a temperature sensitive block in cell division and it is involved in peptidoglycan synthesis or modification [<cite idref="PUB00002282"/>]. The SpoIIIE protein is implicated in intercellular chromosomal DNA transfer [<cite idref="PUB00002282"/>]. </p>
