Establishing how bacterial cells position the division site
… via the combined action of two factors: the Min system and nucleoid occlusion. Both factors have been proposed to prevent Z ring assembly along the length of the cell, allowing it to assemble only once chromosomes segregate and nucleoid occlusion is relieved specifically at midcell. The …

Regulators of Bacterial Cell Division: Investigations of Min Oscillation and Ftsa Activity
… on two proteins that regulate the Z ring: MinD, which is a part of the Min system and important for positioning of the divisome; and FtsA, involved in early and late stages of divisome formation with a speculated role in regulating its constriction and disassembly. In <em>E. coli</em> the …

Physical Aspects of Min Oscillations in Escherichia Coli
… in living cells. Specifically, we studied the Min-system in the bacterium Escherichia coli. It consists of the MinC, the MinD, and the MinE proteins, which play an important role in the correct selection of the cell division site. The Min-proteins oscillate between the two cell poles and …

Organization and Regulation of Proteins Required For Initiation of Cell Division In Escherichia Coli
… order to ensure efficient cell division, and the MinCDE proteins have an important role in restricting the Z ring to midcell. I found that an artificial fusion of the C-terminus of MinC with MinD, instead of inhibiting Z ring formation as expected, restricted FtsA localization to only part of an …

We are what we eat : identifying a regulatory crosstalk between central carbon metabolism and cell division in bacteria
… bacteria has focused on two main regulatory systems, the Min system and nucleoid occlusion. However, an aspect of cell division control that remains often overlooked is the need to coordinate cell cycle events with the nutrient availability. Central Carbon Metabolism (CCM), being the entry …

Molecular Mechanism By Which The Escherichia Coli Nucleoid Occlusion Factor, Slma, Keeps Cytokinesis In Check
… the assembly of the division apparatus and determines the site of cytokinesis. The total amount of FtsZ molecules in a cell significantly exceeds the concentration required for Z-ring formation. Hence, Z-ring formation must be highly regulated, both temporally and spatially. In particular, the …

Functional characterization of the cell division protein MinE from the Gram-negative coccus Neisseria gonorrhoeae
The Min system, comprising MinC, MinD, and MinE, is found in many Gram-negative bacterial species, including the bacillus Escherichia coli (Ec), and the coccus Neisseria gonorrhoeae (Ng). The Min proteins are important to properly initiate cell division in bacteria at the midcell. Previously, it …

Biochemical, structural and functional analysis of the cell division site determinant MinD(Ng): To divide or not to divide
The Min system, constituting MinC, MinD, and MinE proteins plays an essential role in regulating cell division in Gram-negative bacteria. MinD, a peripheral membrane ATPase, functions by recruiting the cell division inhibitor, MinC, to the membrane where it prevents septation. Counteracting this …

EKNOT: Event Knowledge from News and Opinions on Twitter
We present the EKNOT system that automatically discovers major events from online news articles, connects each event to its discussion on Twitter, and provides a comprehensive summary of the events from both news media and social media’s point of view. EKNOT takes a time period as input and outputs …
