The interactions of cell division protein FtsZ with guanine nucleotides.
Prokaryotic cell division protein FtsZ, an assembling GTPase, directs the formation of the septosome between daughter cells. FtsZ is an attractive target for the development of new antibiotics. Assembly dynamics of FtsZ is regulated by the binding, hydrolysis, and exchange of GTP. We have determined the energetics of nucleotide binding to model apoFtsZ from Methanococcus jannaschii and studied ...
متن کاملCell 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 کاملTargeting the Bacterial Division Protein FtsZ.
Similar to its eukaryotic counterpart, the prokaryotic cytoskeleton is essential for the structural and mechanical properties of bacterial cells. The essential protein FtsZ is a central player in the cytoskeletal family, forms a cytokinetic ring at mid-cell, and recruits the division machinery to orchestrate cell division. Cells depleted of or lacking functional FtsZ do not divide and grow into...
متن کاملDirect interaction between the cell division protein FtsZ and the cell differentiation protein SpoIIE.
SpoIIE is a bifunctional protein with two critical roles in the establishment of cell fate in Bacillus subtilis. First, SpoIIE is needed for the normal formation of the asymmetrically positioned septum that forms early in sporulation and separates the mother cell from the prespore compartment. Secondly, SpoIIE is essential for the activation of the first compartment-specific transcription facto...
متن کاملRoles of FtsA and FtsZ in activation of division sites.
Increasing FtsZ induces the formation of minicells at cell poles but does not increase the frequency or timing of central divisions. A coordinate increase in both FtsZ and FtsA, however, increases the frequency of both polar and central divisions.
