Description: Bacillus subtilis SpoIIIE is a member of the FtsK/SpoIIIE family of double-stranded DNA (dsDNA) transporters that are involved in a wide variety of processes in many species, including: conjugation, DNA packaging of eukaryotic and bacterial viruses, chromosome segregation in bacteria, and DNA maintenance in archae. SpoIIIE moves a trapped chromosome across an asymmetric division septum into the forespore during sporulation. To further understand how members of the FtsK/SpoIIIE family interact with their substrates, we investigated the role of the α domain of SpoIIIE during sporulation in B. subtilis, and investigated how SpoIIIE interacts with its substrate DNA during transport by taking advantage of the non-translocating mutant: SpoIIIE36.
