Bacterial sporulation: Pole-to-pole protein oscillation
Sporulating bacteria need to temporally coordinate DNA replication, chromosome partitioning and sporulation initiation. Recent work has shown that one aspect of this coordination lies with the interdependent subcellular localization of two proteins, Spo0J and Soj, and in the Spo0J-dependent spatial oscillation of Soj.
متن کاملRapid pole-to-pole oscillation of a protein required for directing division to the middle of Escherichia coli.
Accurate placement of the division septum at the midpoint of Escherichia coli cells requires the combined action of a general division inhibitor (MinC), a site-specific suppressor of division inhibition (MinE), and an ATPase (MinD) that is required for proper functioning of both MinC and MinE. We previously showed that a functional MinE-Gfp fusion accumulates in a ring structure at/near the mid...
متن کاملMinDE-dependent pole-to-pole oscillation of division inhibitor MinC in Escherichia coli.
By inhibiting FtsZ ring formation near the cell ends, the MinC protein plays a critical role in proper positioning of the division apparatus in Escherichia coli. MinC activity requires that of MinD, and the MinE peptide provides topological specificity by suppressing MinC-MinD-mediated division inhibition specifically at the middle of the cell. We recently presented evidence that MinE not only ...
متن کاملPole-to-pole biogeography of surface and deep marine bacterial communities.
The Antarctic and Arctic regions offer a unique opportunity to test factors shaping biogeography of marine microbial communities because these regions are geographically far apart, yet share similar selection pressures. Here, we report a comprehensive comparison of bacterioplankton diversity between polar oceans, using standardized methods for pyrosequencing the V6 region of the small subunit r...
متن کاملBacterial activity in South Pole snow.
Large populations (200 to 5,000 cells ml(-1) in snowmelt) of bacteria were present in surface snow and firn from the south pole sampled in January 1999 and 2000. DNA isolated from this snow yielded ribosomal DNA sequences similar to those of several psychrophilic bacteria and a bacterium which aligns closely with members of the genus Deinococcus, an ionizing-radiation- and desiccation-resistant...
