Tubulin domain

From Wikipedia, the free encyclopedia
Tubulin/FtsZ family, GTPase domain is an evolutionary conserved protein domain.
This domain is found in all tubulin chains,[1] as well as the bacterial FtsZ family of proteins.[2] These proteins are involved in polymer formation. Tubulin is the major component of microtubules, while 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,[3] this entry is the GTPase domain. FtsZ can polymerise into tubes, sheets, and rings in vitro and is ubiquitous in bacteria and archaea.
