Cell division protein FtsX (IPR004513)

Short name: ABC_transpt_FtsX

Overlapping homologous superfamilies


Family relationships



FtsX is an integral membrane protein encoded in the same operon as signal recognition particle docking protein FtsY and FtsE. FtsE is a hydrophilic nucleotide-binding protein that associates with the inner membrane by means of association with FtsX; FtsE mutants are viable only in high salt, supporting possible roles in cell division, as previously indicated, or in transport [PMID: 10048040]. FtsX is important for bacterial cell division, however its precise function is not yet known [PMID: 17307852, PMID: 16416128]. FtsX is involved in sporulation in the Gram-positive bacterium Bacillus subtilis [PMID: 18573177].
