We have cloned an Enterococcus faecalis gene cluster, cydABCD, which when expressed in Bacillus subtilis results in a functional cytochrome bd terminal oxidase. Our results indicate that E. faecalis V583 cells have the capacity of aerobic respiration when grown in the presence of heme.
CcdA is known to be required for the synthesis of c-type cytochromes in Bacillus subtilis, but the exact function of this membrane protein is not known. We show that CcdA also plays a role in spore synthesis. The expression of ccdA and the two downstream genes yneI and yneJ was analyzed. There is a promoter for each gene, but there is only one transcription terminator, located after the yneJ gene.
Cytochromes of c-type contain covalently bound haem and in bacteria are located on the periplasmic side of the cytoplasmic membrane. More than eight different gene products have been identified as being specifically required for the synthesis of cytochromes c in Gram-negative bacteria. Corresponding genes are not found in the genome sequences of Gram-positive bacteria. Using two random mutagenesis
Heme A is a prosthetic group in many respiratory oxidases. It is synthesised from heme B (protoheme IX) with heme O as an intermediate. In Bacillus subtilis two genes required for heme A synthesis, ctaA and ctaB, have been identified. CtaB is the heme O synthase and CtaA is involved in the conversion of heme O to heme A. A ctaB paralogue, yjdK, has been identified through the B. subtilis genome se
Platform ecosystems are becoming the locus of innovation-driven economies as technology-based platform within the ecosystem acts as the foundation for innovative product and services developed by the networked business community around that platform. At its core, a technology platform shows architectural properties, which once emerged in an industry could play as the de facto template for defining
Open Charge Point Protocol (OCPP) is a widely used open communication protocol between a charging station and its managing network system. The central promising idea of the OCPP is that it is an open standard, which provides a standardized communication language with the flexibility of giving charging station owners right to switch network providers at their own will. This paper investigates the o
Many organizations are adopting business intelligence and analytics systems in order to cope with the increasing digitalization of data intensive environments. In this paper, we study the role of self-service business intelligence (SSBI), a certain capability provided by a business intelligence system, in enabling organizational agility. In particular, the research question we address is as follow
A search for neutral Higgs bosons of the minimal supersymmetric standard model (MSSM) and for a heavneutral Z′ boson is performed using a data sample corresponding to an integrated luminosity of 3.2 fb- 1 from proton–proton collisions at s=13 TeV recorded by the ATLAS detector at the LHC. The heavy resonance is assumed to decay to a τ+τ- pair with at least one τ lepton decaying to final states wit
The large rate of multiple simultaneous proton–proton interactions, or pile-up, generated by the Large Hadron Collider in Run 1 required the development of many new techniques to mitigate the adverse effects of these conditions. This paper describes the methods employed in the ATLAS experiment to correct for the impact of pile-up on jet energy and jet shapes, and for the presence of spurious addit
We present measurements of the elliptic (v2), triangular (v3) and quadrangular (v4) anisotropic azimuthal flow over a wide range of pseudorapidities (−3.5<η<5). The measurements are performed with Pb–Pb collisions at sNN=2.76 TeV using the ALICE detector at the Large Hadron Collider (LHC). The flow harmonics are obtained using two- and four-particle correlations from nine different centrality inte
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|<2.3 and transverse momentum between 0.1 GeV and 22 GeV in a dataset corresponding to an
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
