2. 1. On the cell cycle of Escherichia coli and cell division in Haloferax mediterranei

   Author : Björn Gullbrand; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Branch; division; Escherichia coli; Haloferax mediterranei; replication; segregation; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; mikrobiologi; Microbiology;

   Abstract : Escherichia coli has served as a model organism for prokaryotes for several decades and is perhaps the most well characterised organism on earth. The use of fluorescence microscopy during recent years has contributed substantially to our understanding of the essential cell cycle processes chromosome replication, chromosome segregation and cell division.

4. 2. Cell division in Escherichia coli

   Author : Karl Skoog; Daniel O. Daley; Miguel Vicente; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

   Abstract : The Gram-negative bacterium Escherichia coli is a model system to describe the biochemistry and cell biology of cell division in bacteria. This process can be divided into three major steps. The first step involves the replication of the DNA, followed by an elongation step in which the cells become twice as long. READ MORE

5. 3. Fluorescence Studies of Cell Division in Escherichia coli

   Author : Bill Söderström; Gunnar von Heijne; Jie Xiao; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; E. coli; Cell division; FtsZ; Fluorescence microscopy; FRAP; Biophysics; biofysik;

   Abstract : In Escherichia coli the cell division is carried out by a large dynamic protein complex called the divisome. The divisome assembles in a two-step manner starting with the localization of the eukaryotic tubulin homologue FtsZ to the midcell. Together with other early arriving proteins FtsZ form an intermediate structure called the Z-ring. READ MORE

6. 4. Developmental Control of Cell Division in Streptomyces coelicolor

   Author : Nina Grantcharova; Klas Flärdh; Gerhart Wagner; Yves Brun; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; FtsZ; cell division; Streptomyces; GFP; bacterial development; Mikrobiologi; Microbiology; Mikrobiologi;

   Abstract : Cell division in the Gram-positive bacterium Streptomyces coelicolor starts with the assembly of the tubulin homologue FtsZ into a cytokinetic ring (the Z ring) at the site of septation. In stark contrast to the binary fission of most bacteria, the syncytial hyphal cells of S. READ MORE

7. 5. Studies on cell wall recycling and modification in Gram-negative bacteria

   Author : Michael C. Gilmore; Felipe Cava; Peter A Lind; Teresa Frisan; Jean-François Collet; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptidoglycan recycling; bacterial cell wall; antibiotics; Agrobacterium tumefaciens; Escherichia coli; Legionella pneumophila; mikrobiologi; Microbiology; Biochemistry; biokemi;

   Abstract : The bacterial cell wall is made from peptidoglycan (PG), a heteropolymer which forms a bag-like exoskeleton that envelopes the cell. PG is constantly remodelled during growth and division, and in response to environmental stimuli. READ MORE
