1. The dynamic nature of the bacterial cytoskeleton.

    Experientia. Basel 66(20):3353 (2009) PMID 19641848 PMCID PMC2810845

    Three of the four well-established bacterial cytoskeletal systems-the MreB, MinCDE, and FtsZ systems-undergo a variety of short-range and long-range dynamic behaviors. These include the cellular reorganization of the cytoskeletal elements, in which the proteins redistribute from a predominantly ...

  3. Assembly of the MreB-associated cytoskeletal ring of Escherichia coli.

    Molecular Microbiology 72(1):170 (2009) PMID 19220747

    The Escherichia coli actin homologue MreB is part of a helical cytoskeletal structure that winds around the cell between the two poles. It has been shown that MreB redistributes during the cell cycle to form circumferential ring structures that flank the cytokinetic FtsZ ring and appear to be as...

    Journal of Separation Science 31(22):3829 (2008) PMID 19009537

    LC-MS technique described here is a new way for the separation and direct determination of UV-Vis insensitive inositol phosphates (InsP(2)-InsP(6)). This circumvents the need of radioisotopic labeling and post-column derivatization techniques. The method involves separation of various enzymatica...

    PNAS 104(45):17795 (2007) PMID 17978175 PMCID PMC2077029

    The bacterial actin homolog MreB exists as a single-copy helical cytoskeletal structure that extends between the two poles of rod-shaped bacteria. In this study, we show that equipartition of the MreB cytoskeleton into daughter cells is accomplished by division and segregation of the helical Mre...
