FtsE and FtsX, which are widely conserved homologs of ABC transporters and interact with each other, have important but unknown functions in bacterial cell division. Coimmunoprecipitation of Escherichia coli cell extracts revealed that a functional FLAG-tagged version of FtsE, the putative ATP-binding component, interacts with FtsZ, the bacterial tubulin homolog required to assemble the cytokin...

The antimicrobial activity of the chemokine CXCL10 against vegetative cells of Bacillus anthracis occurs via both bacterial FtsE/X-dependent and-independent pathways. Previous studies established that the FtsE/X-dependent pathway was mediated through interaction of the N-terminal region(s) of CXCL10 with a functional FtsE/X complex, while the FtsE/X-independent pathway was mediated through the ...

The chaperonin GroE (GroEL and the cochaperonin GroES) is the only chaperone system that is essential for the viability of Escherichia coli. It is known that GroE-depleted cells exhibit a filamentous morphology, suggesting that GroE is required for the folding of proteins involved in cell division. Although previous studies, including proteome-wide analyses of GroE substrates, have suggested se...

The FtsEX:PcsB complex forms a molecular machine that carries out peptidoglycan (PG) hydrolysis during normal cell division of the major respiratory pathogenic bacterium, Streptococcus pneumoniae (pneumococcus). FtsX is an integral membrane protein and FtsE is a cytoplasmic ATPase that together structurally resemble ABC transporters. Instead of transport, FtsEX transduces signals from the cell ...

The relationship between returns, volatility and trading volume has interested financial economists and analysts for a number of years. A widely documented result is the positive contemporaneous relationship between price returns and trading volume. This paper investigates the contemporaneous and dynamic relationships between trading volume, returns and volatility for Greek index futures (FTSE/...

High grade serous ovarian carcinoma (HGSC) is a DNA instable tumor and its precursor is commonly found originating from the fimbriated end of the fallopian tube secretory epithelial (FTSE) cells. The local stresses via ovulation and related inflammation are risks for HGSC. In this study, we examined the cellular and molecular responses of FTSE cells to stress. We found that excess intracellular...

UNLABELLED Bacillus anthracis is killed by the interferon-inducible, ELR(-) CXC chemokine CXCL10. Previous studies showed that disruption of the gene encoding FtsX, a conserved membrane component of the ATP-binding cassette transporter-like complex FtsE/X, resulted in resistance to CXCL10. FtsX exhibits some sequence similarity to the mammalian CXCL10 receptor, CXCR3, suggesting that the CXCL10...

In this paper, we propose a new method to build a fault tolerant ATM switch. Using this method, we can build an ATM switch which has two disjoint paths between each input/ output pair. The key component in the proposed switch is a 2 ¥ 2 FTSE (Fault Tolerant Switching Element), which can be used as the basic building block for high speed ATM switches. The design of the FTSE-based fault tolerant ...

This study offers an application of Infinite dimension VAR technique in measuring the performance of Greek and Cypriot financial market efficiency. The model aims to explore the forces driving the performance of a large banks proxy by returns on FTSE/ATHEX20 and FTSE/ATHEX BANKS stock indices during the period of 1997–2009. IVAR analysis can be used as either an alternative or complement to rat...

FtsE and FtsX of Escherichia coli constitute an apparent ABC transporter that localizes to the septal ring. In the absence of FtsEX, cells divide poorly and several membrane proteins essential for cell division are largely absent from the septal ring, including FtsK, FtsQ, FtsI, and FtsN. These observations, together with the fact that ftsE and ftsX are cotranscribed with ftsY, which helps to t...
