Work on two diverse rod-shaped bacteria, Escherichia coli and Bacillus subtilis, has defined
a set of about 10 conserved proteins that are important for cell division in a wide range of …

▪ Abstract FtsZ is a prokaryotic tubulin homolog that assembles into a ring at the future site of
cell division. The resulting “Z ring” forms the framework for the division apparatus, and its …

FtsZ, a GTPase distributed in the cytoplasm of most bacteria, is the major component of the
machinery responsible for division (the divisome) in Escherichia coli. It interacts with …

Cell division in bacteria is mediated by the septal ring, a collection of about a dozen (known)
proteins that localize to the division site, where they direct assembly of the division septum …

Bacterial cells contain a variety of structural filamentous proteins necessary for the spatial
regulation of cell shape, cell division, and chromosome segregation, analogous to the …

Background Cytokinesis in bacteria is mediated by a cytokinetic ring, termed the Z ring,
which forms a scaffold for recruitment of other cell-division proteins. The Z ring is composed …

All cytoskeletal elements known from eukaryotic cells are also present in bacteria, where
they perform vital tasks in many aspects of the physiology of the cell. Bacterial tubulin (FtsZ) …

ABSTRACT In Escherichia coli FtsZ organizes into a cytoskeletal ring structure, the Z ring,
which effects cell division. FtsZ is a GTPase, but the free energy of GTP hydrolysis does not …

▪ Abstract The structural elucidation of clear but distant homologs of actin and tubulin in
bacteria and GFP labeling of these proteins promises to reinvigorate the field of prokaryotic …

FtsZ polymerizes to form a dynamic ring structure called the Z-ring at the midcell of bacteria.
EzrA, a membrane protein, has been shown to prevent the formation of aberrant Z-rings in …
