Cell division protein FtsZ

Gene

ftsZ

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 that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity. Polymerization and bundle formation is enhanced by CbeA.

Enzyme regulationi

Formation of the FtsZ ring is inhibited by SulA, MinCD, DicB and toxins CbtA and CptA. Inhibition by toxin CbtA, SulA or DicB overexpression is neutralized by cytoskeleton bundling-enhancing protein CbeA, while inhibition by toxin CptA is neutralized by antitoxin CptB (PubMed:21166897, PubMed:22239607, PubMed:22515815, PubMed:8752322). Either FtsA or ZipA is required for Z ring formation and stabilization (PubMed:11847116).5 Publications

Expressioni

Inductioni

Repressed 1.3-fold by hydroxyurea (at protein level).1 Publication

Interactioni

Subunit structurei

Homodimer. Polymerizes to form a dynamic ring structure in a strictly GTP-dependent manner. Polymers persist as long as GTP is present and disappear rapidly as soon as it is consumed. Interacts directly with several other division proteins, including FtsA and ZipA. Interacts with polymerization inhibitors SulA, CbtA and CptA. Interacts with MreB and polymerization bundling-enhancing factor CbeA.10 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
