Escherichia coli K-12 substr. MG1655 Polypeptide: cell division protein FtsE



Gene: ftsE Accession Numbers: EG10340 (EcoCyc), b3463, ECK3447

Regulation Summary Diagram: ?

Component of: FtsE/FtsX ABC transporter (summary available)

Summary:
FtsE is the putative ATP-binding protein component of an ATP-binding cassette (ABC) transporter. FtsE dimerizes and associates with the inner membrane via interaction with FtsX, an integral membrane protein [deLeeuw99].

FtsE and FtsX localize to the cell division site; localization is dependent on FtsZ, FtsA and ZipA, but not FtsK, FtsQ, FtsL and FtsI [Schmidt04]. FtsEX is important for assembly or stability of the septal ring under low-salt growth conditions [Schmidt04].

An ftsE null mutant is only viable on high salt medium [deLeeuw99]. ftsE and ftsX are located in an operon with the ftsY gene. ftsY encodes a GTPase which acts as a receptor for the SRP (signal recognition particle) involved in protein targeting [Gill87, Miller94a]. It has been suggested that FtsE and FtsX are not to be required for SRP-mediated targeting [deLeeuw99], although it has been reported that ftsE mutants are affected in translocation of potassium ion pump proteins into the cytoplasmic membrane [Ukai98].

Subunit of: FtsE/FtsX ABC transporter

Subunit composition of FtsE/FtsX ABC transporter = [FtsE]2[FtsX]2
         cell division protein FtsE = FtsE (extended summary available)
         cell division protein FtsX = FtsX (summary available)

Summary:
FtsE and FtsX are members of the ABC superfamily of transporters [Saurin99]. FtsE is the putative ATP-binding protein and FtsX is the putative membrane component. ftsE and ftsX were originally identified as conditional lethal mutants which failed to septate at the non-permissive temperature, implying a role in cell division [Taschner88]. FtsE and FtsX have been purified and shown to interact by co-immunoprecipitation [deLeeuw99]. The FtsEX complex probably functions as an ATP-dependent transporter which has a role in cell division and possibly salt transport.
