Cell division and transcription of ftsZ.
For normal cell division, the ftsZ gene must be transcribed from a number of promoters that are located within the proximal upstream genes (ddlB, ftsQ, and ftsA). We show that the main promoters have identical responses to changes in growth rate, i.e., under all conditions, the frequency of transcription per septum formed is approximately constant and independent of cell size or growth rate per...
متن کاملFtsZ-less prokaryotic cell division as well as FtsZ- and dynamin-less chloroplast and non-photosynthetic plastid division
The chloroplast division machinery is a mixture of a stromal FtsZ-based complex descended from a cyanobacterial ancestor of chloroplasts and a cytosolic dynamin-related protein (DRP) 5B-based complex derived from the eukaryotic host. Molecular genetic studies have shown that each component of the division machinery is normally essential for normal chloroplast division. However, several exceptio...
متن کاملInteraction between cell division proteins FtsE and FtsZ.
FtsE and FtsX, which are widely conserved homologs of ABC transporters and interact with each other, have important but unknown functions in bacterial cell division. Coimmunoprecipitation of Escherichia coli cell extracts revealed that a functional FLAG-tagged version of FtsE, the putative ATP-binding component, interacts with FtsZ, the bacterial tubulin homolog required to assemble the cytokin...
متن کاملCell division without FtsZ--a variety of redundant mechanisms.
Until 1998 it looked like all bacteria and archaea used a universal cytokinetic machine based on FtsZ. A dozen completely sequenced bacterial genomes all had an ftsZ gene, as did the several sequenced archaeal genomes. Then in 1998–1999 two species of Chlamydia were sequenced and found to have no ftsZ (Stephens et al., 1998; Kalman et al., 1999). Enthusiasts of FtsZ could hold out some hope for...
متن کاملFtsZ regulates frequency of cell division in Escherichia coli.
Cell division is regulated so that it occurs only once per cell cycle. In Escherichia coli, a rod-shaped bacterium, division normally takes place at the center of the long axis of the cell; however, in the minicell mutant, division can also take place at the cell pole. Such divisions take place at the expense of normal divisions, resulting in an overall increase in nucleated cell length. We rep...
