This family includes the tubulin alpha, beta and gamma chains, as well as the bacterial FtsZ family of proteins. Members of this family are involved in polymer formation. FtsZ is the polymer-forming protein of bacterial cell division. It is part of a ring in the middle of the dividing cell that is required for constriction of cell membrane and cell envelope to yield two daughter cells. FtsZ and tubulin are GTPases. FtsZ can polymerise into tubes, sheets, and rings in vitro and is ubiquitous in eubacteria and archaea. Tubulin is the major component of microtubules.	Domain

This domain is found at the C-terminal end of Tubulin-like protein TubZ from Clostridium botulinum C phage and similar sequences found in tailed bacteriophages and prophages mainly from Clostridium bacteria. TubZ is a tubulin-like, filament forming GTPase. This protein adopts a tubulin/FtsZ protein family fold organised into two domains, a canonical N-terminal GTP-binding domain, and a C-terminal GTPase domain (this entry) [1].	Domain
