1. Cell Division in genus Corynebacterium: protein-protein interaction and molecular docking of SepF and FtsZ in the understanding of cytokinesis in pathogenic species
ABSTRACT The genus Corynebacterium includes species of great importance in medical, veterinary and biotechnological fields. The genus-specific families (PLfams) from PATRIC have been used to observe conserved proteins associated to all species. Our results showed a large number of conserved proteins that are associated with the cellular division process. Was

2. Prokaryotic cells: structural organisation of the cytoskeleton and organelles
For many years, prokaryotic cells were distinguished from eukaryotic cells based on the simplicity of their cytoplasm, in which the presence of organelles and cytoskeletal structures had not been discovered. Based on current knowledge, this review describes the complex components of the prokaryotic cell cytoskeleton, including (i) tubulin homologues composed

3. Expressão e caracterização de proteínas envolvidas na via da quinase mTOR e na divisão celular bacteriana / Expression and characterization of proteins involved in the mTOR kinase pathway and bacterial cell division
A mTOR é uma via de sinalização muito conservada que controla o crescimento celular em resposta à presença de nutrientes e fatores de crescimento. A desregulação dessa via em humanos está relacionada a doenças como câncer e diabetes. A quinase TOR é ativada na presença de aminoácidos e recentemente descobriu-se que as pequenas GTPases da famíli

4. Genes involved in cell division in mycoplasmas
Bacterial cell division has been studied mainly in model systems such as Escherichia coli and Bacillus subtilis, where it is described as a complex process with the participation of a group of proteins which assemble into a multiprotein complex called the septal ring. Mycoplasmas are cell wall-less bacteria presenting a reduced genome. Thus, it was important

5. Identification and characterization of new modulators of division in B. subtilis / Identificação e caracterização de novos moduladores da divisão em Bacillus subtilis
In prokaryotes, the main form of reproduction is binary fission, which allows the mother-cell to give origin the two daughter-cells, with identical genetic material. In Bacillus subtilis, this process is performed by the divisome, a complex formed for approximately sixteen proteins that leads to the constriction of the membrane and the wall, creating the div

7. Genetic and Functional Analyses of the Conserved C-Terminal Core Domain of Escherichia coli FtsZ
In Escherichia coli, FtsZ is required for the recruitment of the essential cell division proteins FtsA and ZipA to the septal ring. Several C-terminal deletions of E. coli FtsZ, including one of only 12 amino acids that removes the highly conserved C-terminal core domain, failed to complement chromosomal ftsZ mutants when expressed on a plasmid. To identify

8. Direct observation of the enhancement of noncooperative protein self-assembly by macromolecular crowding: Indefinite linear self-association of bacterial cell division protein FtsZ
Recent measurements of sedimentation equilibrium and sedimentation velocity have shown that the bacterial cell division protein FtsZ self-associates to form indefinitely long rod-like linear aggregates in the presence of GDP and Mg2+. In the present study, the newly developed technique of non-ideal tracer sedimentation equilibrium was used to measure th

9. Colocalization of Plastid Division Proteins in the Chloroplast Stromal Compartment Establishes a New Functional Relationship between FtsZ1 and FtsZ2 in Higher Plants1
Chloroplast division is driven by a macromolecular complex containing components that are positioned on the cytosolic surface of the outer envelope, the stromal surface of the inner envelope, and in the intermembrane space. The only constituents of the division apparatus identified thus far are the tubulin-like proteins FtsZ1 and FtsZ2, which colocalize to r

10. Colocalization of cell division proteins FtsZ and FtsA to cytoskeletal structures in living Escherichia coli cells by using green fluorescent protein
In the current model for bacterial cell division, FtsZ protein forms a ring that marks the division plane, creating a cytoskeletal framework for the subsequent action of other proteins such as FtsA. This putative protein complex ultimately generates the division septum. Herein we report that FtsZ and FtsA proteins tagged with green fluorescent protein (

11. The 75-kilodalton antigen of Bartonella bacilliformis is a structural homolog of the cell division protein FtsZ.
A genomic library of Bartonella bacilliformis was constructed and screened with human anti-Bartonella serum from a patient with the chronic, verruga peruana phase of bartonellosis. An immunoreactive clone isolated from this library was found to code for a 591-amino-acid protein with a high degree of sequence similarity to the FtsZ family of proteins. The deg

12. Interactions between heterologous FtsA and FtsZ proteins at the FtsZ ring.
FtsZ and FtsA are essential for cell division in Escherichia coli and colocalize to the septal ring. One approach to determine what regions of FtsA and FtsZ are important for their interaction is to identify in vivo interactions between FtsA and FtsZ from different species. As a first step, the ftsA genes of Rhizobium meliloti and Agrobacterium tumefaciens w
