Description | This entry represents a GTPase domain found in all tubulin chains, such as tubulin alpha, beta and gamma chains, plant ARC3 and prokaryotic FtsZ and CetZ proteins [ , ]. These proteins are involved in polymer formation. Tubulin is the major component of microtubules, while FtsZ (homologue of eukaryotic tubulin) 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 can polymerise into tubes, sheets, and rings in vitro and is ubiquitous in bacteria and archaea. CetZ co-exists with FtsZ in many archaea. Cetz does not affect cell division, instead, it is involved in cell shape control []. Arabidopsis chloroplast protein ARC3 (At1g75010) is a Z-ring accessory protein involved in the initiation of plastid division and division site placement [, ]. |
