A search for W′bosons in events with one lepton (electron or muon) and missing transverse momentum is presented. The search uses 3.2 fb−1of pp collision data collected at s=13 TeV by the ATLAS experiment at the LHC in 2015. The transverse mass distribution is examined and no significant excess of events above the level expected from Standard Model processes is observed. Upper limits on the W′boson

We present measurements of two-particle correlations with neutral pion trigger particles of transverse momenta 8>pT trig>16 GeV/c and associated charged particles of 0.5>pT assoc>10 GeV/c versus the azimuthal angle difference Δφ at midrapidity in pp and central Pb–Pb collisions at sNN=2.76 TeV with ALICE. The new measurements exploit associated charged hadrons down to 0.5 GeV/c, which significantl

Measurements of the per-event charged-particle yield as a function of the charged-particle transverse momentum and rapidity are performed using p+Pb collision data collected by the ATLAS experiment at the LHC at a centre-of-mass energy of sNN=5.02TeV. Charged particles are reconstructed over pseudorapidity |η|

A search is presented for dark matter produced in association with a hadronically decaying W or Z boson using 3.2 fb-1 of pp collisions at √ s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet compatible with a W or Z boson and with large missing transverse momentum are analysed. The data are consistent with the Standard Model predictions and are inte

The aerobic respiratory system of Bacillus subtilis 168 is known to contain three terminal oxidases: cytochrome caa3, which is a cytochrome c oxidase, and cytochrome aa3 and bd, which are quinol oxidases. The presence of a possible fourth oxidase in the bacterium was investigated using a constructed mutant, LUH27, that lacks the aa3 and caa3 terminal oxidases and is also deficient in succinate:men

Previous research on collaboration in social work practice shows that conflicts among collaborating authorities and organizations and that include cooperating actors are common. In this study, I have analyzed a successful dimension of the phenomenon “cooperation.” The purpose of the study is to analyze examples of successful cooperation in Swedish social work practice. This study presents an analy

We demonstrate that the cccB gene, identified in the Bacillus subtilis genome sequence project, is the structural gene for a 10-kDa membrane-bound cytochrome c551 lipoprotein described for the first time in B. subtilis. Apparently, CccB corresponds to cytochrome c551 of the thermophilic bacterium Bacillus PS3. The heme domain of B. subtilis cytochrome c551 is very similar to that of cytochrome c55

Clusters of genes encoding enzymes for tetrapyrrole biosynthesis were cloned from Bacillus sphaericus, Bacillus stearothermophilus, Brevibacillus brevis and Paenibacillus macerans. The sequences of all hemX genes found, and of a 6.3 kbp hem gene cluster from P. macerans, were determined. The structure of the hem gene clusters was compared to that of other Gram-positive bacteria. The Bacillus and B

The sequence of the N-terminal end of the deduced ctaC gene product of Bacillus species has the features of a bacterial lipoprotein. CtaC is the subunit II of cytochrome caa3, which is a cytochrome c oxidase. Using Bacillus subtilis mutants blocked in lipoprotein synthesis, we show that CtaC is a lipoprotein and that synthesis of the membrane-bound protein and covalent binding of heme to the cytoc

The modified nucleoside 2-methylthio-N-6-isopentenyl adenosine (ms(2)i(6)A) is present in position 37 (adjacent to and 3' of the anticodon) of tRNAs that read codons beginning with U except tRNA(I,V)(Ser) in Escherichia coli, In Salmonella typhimurium , 2-methylthio-N-6-(cis-hydroxy)isopentenyl adenosine (ms(2)io(6)A; also referred to as 2-methylthio cis-ribozeatin) is found in tRNA, most likely i

Succinate:quinone reductase is a membrane-bound enzyme of the citric acid cycle and the respiratory chain. Carboxin is a potent inhibitor of the enzyme of certain organisms. The bacterium Paracoccus denitrificans was found to be sensitive to carboxin in vivo, and mutants that grow in the presence of 3'-methyl carboxin were isolated. Membranes of the mutants showed resistant succinate:quinone reduc

Electron paramagnetic resonance (EPR) studies of succinate:ubiquinone oxidoreductase (SQR) from Paracoccus denitrificans have been undertaken in the purified and membrane-bound states, Spectroscopic ''signatures'' accounting for the three iron-sulfur clusters (2Fe-2S, 3Fe-4S, and 4Fe-4S), cytochrome b, flavin, and protein-bound ubisemiquinone radicals have been obtained in air-oxidized, succinate-

Escherichia coli CcmA, CcmB and CcmC polypeptides are required for cytochrome c synthesis and are thought to constitute the subunits of an ABC-type transporter as judged from sequence data, Using a periplasmic reporter system based on Bacillus subtilis cytochrome c-550 and E. coli cytochrome b-562 we show that the synthesis of the b-type cytochrome in the periplasm is normal in E, coli ccmA and cc

Cytochromes of the c type contain covalently bound heme. In bacteria, they are located on the outside of the cytoplasmic membrane. Cytochrome c synthesis involves export of heme and apocytochrome across the cytoplasmic membrane followed by ligation of heme to the polypeptide. Using radioactive protoheme IX produced in Escherichia coli, we show that Bacillus subtilis can use heme from the growth me

The gram-positive, endospore-forming bacterium Bacillus subtilis contains several membrane-bound c-type cytochromes. We have isolated a mutant pleiotropically deficient in cytochromes c. The responsible mutation resides in a gene which we have named ccdA (cytochrome c defective). This gene is located at 173 degrees on the B. subtilis chromosome. The ccdA gene was found to be specifically required

Many succinate:quinone oxidoreductases in bacteria and mitochondria, i.e, succinate:quinone reductases and fumarate reductases, contain in the membrane anchor a cytochrome b whose structure and function is poorly understood, Based on biochemical data and polypeptide sequence information, we show that the anchors in different organisms are related despite an apparent diversity in polypeptide and he

Synthesis of heme A from heme B (protoheme IX) most likely occurs in two steps with heme O as an intermediate. Bacillus subtilis CtaB, an integral membrane protein, functions in farnesylation of heme B to form heme O. CtaA, also a membrane protein, is required for heme A synthesis from heme O and appears to be a monooxygenase and/or a dehydrogenase. Wild-type ctaA and ctaB expressed together from

We have identified an operon in Bacillus subtilis, designated qcr, that is thought to encode a quinone: cytochrome c reductase. Northern (RNA blot) analysis suggests a tricistronic operon. The operon is located at about 200 degrees on the B. subtilis map. Disruption of the operon leads to loss of a 22-kDa cytochrome c from membrane preparations. The structure of the putative protein products of th
