Team maps targets with hopes of blocking reproduction and rendering infection down for the count In any battle, sizing up one's opponent is a critical first step. For researchers fighting a bacterial infection, that means assessing every nook and cranny of the malicious microorganism and identifying which ones to attack. At the Center for Biological Research of the Spanish Research Council in Madrid, scientists are devising maneuvers they hope will take out bacteria at their molecular knees,...

A team of biologists has unraveled the biochemistry of how bacteria so precisely time cell division, a key element in understanding how all organisms from bacteria to humans use their biological clocks to control basic cellular functions. The discovery, detailed in the February 19 issue of the journal Cell, provides important clues to how the biological clocks of bacteria and other "prokaryotic" cells"”which lack cell nuclei"”evolved differently from that of "eukaryotic" cells...

A protein vital for correct chloroplast division in plants is able to take on a similar role in bacterial cells, according to research published today in the open access journal BMC Microbiology. The Arabidopsis thaliana Min protein (AtMinD) localizes in E. coli cells' polar regions keeping cell division at its correct central location, yet unlike its E. coli homologue, AtMinD does not oscillate. Making certain that E. coli cells divide in the centre is down to Min proteins (MinC, D and E)....
