Cell division protein FtsQ

Gene

ftsQ

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic. May control correct divisome assembly.UniRule annotation2 Publications

Interactioni

Subunit structurei

Part of a complex composed of FtsB, FtsL and FtsQ. The complex can be formed before its localization to the division site. This tripartite complex can be divided further into a subcomplex of FtsB and FtsL, which forms in the absence of FtsQ. Interacts with FtsA, FtsK, FtsL, FtsB, FtsW, FtsI, FtsN, FtsX and YmgF.UniRule annotation4 Publications

Domaini

The C-terminal periplasmic region is necessary and sufficient for septal targeting. The transmembrane region contributes to localization to the cell division site. Three periplasmic subdomains are involved in the interactions with other cell division proteins. Localization and recruitment require two separate domains.5 Publications
