Crystal structure of the SOS cell division inhibitor SulA and in complex with FtsZ.
SulA halts cell division in Escherichia coli by binding to the major component of the division machinery FtsZ. We have solved the crystal structure of SulA alone and in complex with FtsZ from Pseudomonas aeruginosa. SulA is expressed when the SOS response is induced. This is a mechanism to inhibit cell division and repair DNA in the event of DNA damage. FtsZ is a tubulin-like protein that forms...
متن کاملFtsz Ring Formation at the Chloroplast Division Site in Plants
Among the events that accompanied the evolution of chloroplasts from their endosymbiotic ancestors was the host cell recruitment of the prokaryotic cell division protein FtsZ to function in chloroplast division. FtsZ, a structural homologue of tubulin, mediates cell division in bacteria by assembling into a ring at the midcell division site. In higher plants, two nuclear-encoded forms of FtsZ, ...
متن کاملEscherichia coli division inhibitor MinCD blocks septation by preventing Z-ring formation.
The min system spatially regulates division through the topological regulation of MinCD, an inhibitor of cell division. MinCD was previously shown to inhibit division by preventing assembly of the Z ring (E. Bi and J. Lutkenhaus, J. Bacteriol. 175:1118-1125, 1993); however, this was questioned in a recent report (S. S. Justice, J. Garcia-Lara, and L. I. Rothfield, Mol. Microbiol. 37:410-423, 20...

15 صفحه اولEffect of minCD on FtsZ ring position and polar septation in Bacillus subtilis.
We examined the pattern of FtsZ localization in a Bacillus subtilis minCD mutant. When grown in minimal medium, the majority (approximately 89%) of the minCD mutant cells with an FtsZ ring had a single, medially positioned FtsZ ring. These results indicate that genes in addition to minCD function to restrict the number and position of FtsZ rings. When grown in rich medium, greater than 50% of t...
