PFAM accession number:PF11983
Interpro abstract (IPR021873):

FtsA is essential for bacterial cell division, and co-localizes to the septal ring with FtsZ. It has been suggested that the interaction of FtsA-FtsZ has arisen through coevolution in different bacterial strains [ (PUBMED:9352931) ].

This C-terminal domain is found in FtsA from Firmicutes (Gram-positive bacteria). It acts as an intra-molecular switch, triggered by ATP, to promote polymerisation of the whole protein and to attach it to the membrane [ (PUBMED:25425238) ].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry DUF3484
