This article reports that investigators from England have reported localization of MreB in Rhodobacter sphaeroides under conditions causing changes in cell shape and membrane structure. The study was conducted by P.M. Slovak and colleagues, University of Oxford, Oxford, England. Slovak and colleagues published their study in the "Journal of Bacteriology." MreB is thought to be a bacterial actin homolog that defines the morphology of rodshaped bacteria. R. sphaeroides changes shape, from a rod to coccobacillus, and undergoes extensive cytoplasmic membrane invagination when it switches from aerobic to photoheterotrophic growth.

The article cites a study which states that Caulobacter crescentus requires RodA and MreB for stalk synthesis and prevention of ectopic pole formation. Caulobacter crescentus cells treated with amdinocillin, an antibiotic which specifically inhibits the cell elongation transpeptidase penicillin binding protein 2 in Escherichia coli, exhibit defects in stalk elongation and morphology, indicating that stalk synthesis may be a specialized form of cell elongation, wrote researcher J.K. Wagner and colleagues, in the "Journal of Bacteriology."

The article cites a study that reported on the analysis of MinD mutations that reveals residues required for MinE stimulation of the MinD ATPase and residues required for MinC interaction. The MinD ATPase is critical to the oscillation of the Min proteins, which limits formation of the Z ring to midcell. In the presence of ATP, MinD binds to the membrane and recruits MinC, forming a complex that can destabilize the cytokinetic Z ring, wrote researcher H.J. Zhou and colleagues, in the "Journal of Bacteriology."

The article reports on a study that suggests that caulobacter crescentus requires RodA and MreB for stalk synthesis and prevention of ectopic pole formation. According to the study conducted by researcher J.K. Wagner and colleagues, published in a 2005 issue of the "Journal of Bacteriology," C. crescentus cells treated with amdinocillin, an antibiotic which specifically inhibits the cell elongation transpeptidase penicillin binding protein 2 in Escherichia coli, exhibit defects in stalk elongation and morphology, indicating that stalk synthesis may be a specialized form of cell elongation.

This article presents findings of a study previously published in the "Journal of Bacteriology," conducted by researcher H.J. Zhou. Researchers from the United States have reported on the analysis of MinD mutations that reveals residues required for MinE stimulation of the MinD ATPase and residues required for MinC interaction. The MinD ATPase is critical to the oscillation of the Min proteins, which limits formation of the Z ring to midcell. In the presence of ATP, MinD binds to the membrane and recruits MinC, forming a complex that can destabilize the cytokinetic Z ring. MinE, which is also recruited to the membrane by MinD, displaces MinC and stimulates the MinD ATPase, resulting in the oscillation of the Min proteins.
