Full textCotranslational translocation of proteins across or into membranes is a vital process in all kingdoms of life. It requires targeting of the translating ribosome to the membrane by the signal recognition particle (SRP), an evolutionary conserved ribonucleoprotein particle. SRP recognizes signal sequences of nascent protein chains emerging from the ribosome. Subsequent binding of SRP leads to pausing of peptide elongation and docking to the membrane-bound SRP receptor. Here, the 12 Å cryo-electron microscopy structure of a targeting complex is presented consisting of mammalian SRP bound to an active 80S ribosome carrying a signal sequence. A molecular model of SRP in this functional conformation was generated. The model reveals how the S-domain of SRP contacts the large ribosomal subunit at the nascent chain exit site to bind the signal sequence, and that the Alu-domain reaches into the elongation factor binding site of the ribosome explaining its elongation arrest activity. A molecular model of the first steps of protein targeting is presented. Moreover, also the docking step has been visualized by solving a cryo-EM structure of the ribosome-SRP complex bound to the SRP receptor. This structure provides first hints regarding the mechanism of ribosome transfer to the translocon. As a side result the position of the functionally significant ribosomal protein L30e has been identified in the high resolution maps of the wheat germ ribosome.

Full textBecker, Thomas. "Strukturen von eEF3 und Sec61 als aktive ribosomale Liganden." Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät I, 2007. http://dx.doi.org/10.18452/15621.
Full textThis work presents cryo-EM structures of two active ribosomal ligands in yeast, namely eEF3 and Sec61. Protein synthesis requires two canonical elongation factors in all kingdoms. These are the GTPases eEF1A (EF-Tu in prokaryotes) and eEF2 (EF-G in prokayotes). In fungi, a third elongation factor eEF3 is required, which belongs to the ATP-binding cassette- (ABC-) protein family. This factor is essential for the binding of the aminoacyl-tRNA-eEF1A-GTP ternary complex to the A site of the ribosome and has been suggested to do so by facilitating the clearance of deacyl-tRNA from the ribosomal E-site. The cryo-EM structure of the ATP-bound form of eEF3 in complex with an 80S ribosome shows that eEF3 binds the ribosome in the post-translocational conformation using a novel binding site. From there the affinity for tRNA in the ribosomal E site could be easily modified. Using the crystal structure of eEF3, a molecular model for eEF3 was generated, which provides the structural basis for the activity of an ABC protein in the context of translation. In co-translational translocation the trimeric Sec61-complex serves as a signal sequence-gated protein-conducting channel (PCC) which allows the translocation of a secetory protein through and the integration of a membrane protein into the lipid bilayer of the ER. Bound to a ribosome, the active PCC seems to have an oligomeric structure consisting of several copies of Sec61-trimers. The crystal structure of an inactive PCC, however, shows only a single heterotrimer (monomer) which could also be functional in the active state. The cryo-EM structure of the active PCC in complex with a translating ribosome shows the hitherto most detailed electron density map for the PCC. The most characteristic feature is a funnel-shaped off-centered pore at the cytosolic side. Several models for the active state were docked into the EM-density. Although a precise molecular interpretation is limited by the resolution (12, 3 Å), a single copy of an opened Sec61-heterotrimer seems to be the most reasonable fit for the density.

Full textPentameric ligand-gated ion channels (pLGICs) are crucial for the conversion of chemical to electrical signaling in the nervous system of mammals. Dysfunction in these channels has been found to be connected to several diseases including epilepsy, schizophrenia, Alzheimer’s, and autism, making them the target of a wide variety of therapeutic agents. However, studying eukaryotic channels is challenging so the discovery of prokaryotic homologs that are much easier to study has thus greatly helped in the understanding of the structure and function in this family of proteins. In this project, a prokaryotic pLGIC called DeCLIC was produced and purified from Escherichia coli. Structural determination of the channel was pursued using cryo-electron microscopy at a low pH and in the presence of calcium. An electron density at 3.4 Å resolution was achieved and compared to previously determined structures at different conditions in an attempt to determine the structural modulation of calcium and pH. Results show multiple differences in channel conformation in the presence and absence of calcium as well as in different pH conditions. Furthermore, analysis of the determined electron density suggests a possible intermediate state at low pH in the presence of calcium.

Full textDetta är ett examensarbete som genomförts hos Göteborg Energi AB och syftar till att utreda omkryogen uppgradering av biogas med fördel kan ske genom att producera nödvändig kyla medvärmedriven absorptionskylmaskin. Göteborg Energi är en av tre parter som tillsammans ska bygga enbiogasanläggning i Lidköping som ska vara i drift 2010. Anläggningen ska producera 30 GWhflytande biogas per år.
Arbetet utreder om det är fördelaktigt ur ekonomiskt, energimässigt och miljömässigt perspektiv attuppgradera biogas med kryogen teknik med värmeproducerad kyla. En jämförelse görs först medkryogen teknik där kylan är producerad med el och sen med andra uppgraderingstekniker. Som stödhar två olika processimuleringsprogram används, Hysys och DESIGN II.
Resultatet visar att energianvändningen ökar då värmedriven kyla används i jämförelse med kylaproducerad med el. 0,47 kW/Nm3 rågas för kryo med absorptionskyla och 0,29 kW/Nm3 rågas medel. Om det finns avsättning för spillvärmen kan energianvändningen i uppgraderingen minska till 0,29kW/Nm3 rågas och 0,15 kW/Nm3 rågas för systemet med värmedriven respektive eldriven kyla. Ijämförelse med andra uppgraderingstekniker ligger 0,47 kW/Nm3 bland de teknikerna med högstenergianvändning medans 0,29 kW/Nm3 placerar sig bland de teknikerna med lägstenergianvändning.
Resultat visar att klimatpåverkan från uppgraderingen, som kommer av metanslip och elanvändningen,minskar marginellt om kylan produceras med värme istället för el. Resultatet varierar mycket beroendepå hur koldioxidutsläppen från marginalelen beräknas. I jämförelse med andra uppgraderingsteknikerligger kryo lägre än de flesta andra. Undantaget är COOAB-tekniken som är överlägset bäst tack varalågt metanslip och liten elanvändning.
Ekonomisk jämförelse med andra uppgraderingstekniker visar att kostnaden för energianvändningenligger i samma nivå som övriga uppgraderingstekniker i jämförelsen, ca 0,03 kr/kWh uppgraderad gas.Om det finns avsättning för spillvärmen sjunker kostnaden till 0,024 och 0,02 kr/kWh uppgraderad gasför kryoteknik med kyla ifrån värme respektive el.
Min slutsats är att utnyttjande av spillvärmen är av stor vikt för att få god ekonomi och lågenergianvändning med kryogen uppgradering. En marginellt förbättrad miljöprestanda kan erhållas omnödvändig kyla produceras med värme istället för el då kryogen uppgradering används. Annars är detalltid mer fördelaktigt att använda el för att producera nödvändig kyla.
This is a master thesis that has been carried out at Göteborg Energi AB. It refers to investigate ifcryogenic upgrading of biogas with advantage can be done by producing necessary cold with a heatdriven absorption cooling machine. Göteborg Energi is one of three actors that together will build abiogas plant in Lidköping that will be up and running in 2010. The plant will produce 30 GWhliquefied biogas annually.
This thesis investigastes whether it is advantageous, to upgrade biogas with heat driven cooling, in aperspective of economy, energy use and environment. It compares cryogenic upgrading with coldproduced by electricity, but also by other techniques. Two different process simulation softwares havebeen used as support to this thesis; Hysys and DESIGN II.
The result shows that energy usage increases when the necessary cold is produced with heat instead ofelectricity; 0,47 kW/Nm3 rawgas for cryo upgrade with absorptions cooling and 0,29 kW/Nm3 rawgaswith cold produced by electricity. If it’s possible to use the waste heat to warm the digester, the energyconsumption for the upgrading can be reduced to 0,29 kW/Nm3 for the system with heat-driven cold,and 0,15 kW/Nm3 rawgas for cold produced by electricity. In comparison with other techniques forupgrading, 0,47 kW/Nm3 rawgas is a high value while 0,29 kW/Nm3 rawgas is among the lowestvalues for energy use.
The impact on the climate emerges from the use of electricity and when methane slips out from theupgrading plant. The result shows that the impact on the climate is slightly decreased for cryogenicupgrading when the cold is produced with a heat driven absorption machine instead of electricity. Theresult varies a lot due to how one calculate the emission of carbon dioxide from the electricity on themargin. In comparison with other upgrading techniques, the climate impact from cryogenic upgradingis less, other than the COOAB-technique that is superior because of its low methane slip and lowdemand of electricity.
An economical comparison shows that the cost for energy usage is about the same for cryogenic as forother techniques; approximately 0,03 SEK/kWh upgraded gas. If one can utilize the waste heat, thecost would be decreased to 0,024 and 0,02 SEK/kWh upgraded gas for the system with cryogenicupgrading with cooling from absorption machine respectively cooling produced with electricity.
My conclusion is that the utilization of the waste heat is essential if one wishes to get good economyand low energy use for the upgrading of biogas with cryogenic methods. A slightly increasedenvironmental improvement can be received if one change the cold production from electricity to heat,otherwise it is always more advantageous to use electricity for cryogenic methods.

Full textENGLISH ABSTRACT: This study focuses on the grammatical properties and syntactic derivation of KRY (“get”)-passives in Afrikaans. Analyses of the corresponding phenomenon in other West-Germanic languages are examined and used as background for the study. The aim of the study is to provide a minimalist analysis of the internal structure of Afrikaans KRY-passives; no such analysis has to date been attempted within the framework of Minimalist Syntax. As an introduction to the phenomenon in Afrikaans, some grammatical background about kry and its syntactic distribution is provided, with special attention paid to the use of this verb in passive constructions. A new analysis of Afrikaans KRY-passives is put forward involving a small clause structure and a light verb component. The main hypothesis of the analysis is that eventive and stative KRY-passives are derived in basically the same manner, the important difference being the presence of a [process] and a [stative] feature, respectively, on the small clause light verb. This hypothesis provides support for the idea that the eventual eventive or stative interpretation of the structure is a consequence of the derivational process rather than being based on lexical features that are already present at the start of the derivation.
AFRIKAANSE OPSOMMING: Hierdie studie fokus op die grammatikale eienskappe en sintaktiese afleiding van KRY-passiewe in Afrikaans. Analises van die ooreenstemmende verskynsel in ander Wes-Germaanse tale word ondersoek en as vertrekpunt vir die studie gebruik. Die doel van die studie is om ‟n minimalistiese analise van die interne struktuur van Afrikaanse KRY-passiewe te ontwikkel; so ‟n analise is nog nie tevore binne die raamwerk van Minimalistiese Sintaksis aangebied nie. As algemene inleiding tot die verskynsel in Afrikaans, word enkele aspekte van kry se grammatikale eienskappe en sintaktiese verspreiding beskryf, met besondere klem op die gebruik van hierdie werkwoord in passiefkonstruksies. ‟n Nuwe analise van KRY-passiewe in Afrikaans word voorgestel, een wat gebruik maak van ‟n beknopte sin (“small clause”)-struktuur en ‟n ligte werkwoord (“light verb”)-komponent. Die vernaamste hipotese van die analise is dat gebeurtenis (“eventive”) en toestand (oftewel statief, “stative”) KRY-passiewe wesenlik op dieselfde manier afgelei word, met een belangrike verskil, naamlik die teenwoordigheid van, onderskeidelik, ‟n [proses]- en ‟n [statief]-kenmerk by die beknopte sin se ligte werkwoord. Dié hipotese verleen steun aan die idee dat die uiteindelike gebeurtenis- of toestand-interpretasie van die struktuur die gevolg is van die afleidingsproses, en dus nie gebaseer is op leksikale kenmerke wat reeds teenwoordig is by die aanvang van die afleiding nie.

Full textIn this thesis, the endocytosis and trafficking pathways of two different biologically relevant nanoparticles, namely dendritic polyglycerol sulfate coated gold nanoparticles (dPGS-np) and polyethyleneimine coated gold nanoparticles (PEI-np) were investigated via cryo soft X-ray tomography. Both nanoparticles were found to be endocytosed predominantly via macropinocytosis, and most nanoparticles became localized to endosomes, multivesicular bodies and lysosomes. Despite these similarities in trafficking, there were also key differences. Some dPGS-np were found in lipid droplets but no PEI nanoparticles were found in this compartment. At a concentration of 0.13 nM, PEI-np were observed to induce extensive rupture of lysosomes, leading to significant levels of cytoplasmic escape and nuclear entry. In contrast, no evidence for lysosomal rupture with dPGS-np was detected, and concomitantly very low levels of cytoplasmic escape and no nuclear entry were found. Interestingly, when the PEI-np concentration was reduced by ten-fold, a switch in the endocytosis pathway from macropinocytosis to a putative caveolae-mediated endocytosis was observed. Importantly, under these conditions, PEI nanoparticles no longer induced lysosomal rupture. This lack of lysosomal rupture at the lower concentration was correlated with reduced cellular damage, and so has important implications for use of PEI in gene delivery. Most surprisingly, both nanoparticle types were found to induce similar global cytoplasmic alterations in the cells. These cytoplasmic alterations could reflect important physiological changes, but further work is required to determine this. Our observations suggest that the behavior of biologically relevant nanoparticles might become more predictable in the future by further application of systematic studies.

Full textIn this master’s thesis real settlements for the over consolidated clay below Arenahallen in Halmstad are compared with two different models for settlement calculations; Chalmersmodellen without creep and Chalmersmodellen with creep. Chalmersmodellen with creep is based on Terzaghi’s consolidation theory with an addition to creep. The purpose has been to find out whether Chalmersmodellen with creep can be used for this clay or if Chalmersmodellen without creep should be used instead. The problem has been solved with detailed studies of literature, sampling of undisturbed flasks of clay with geotechnical boring trailer and tries of compression with an odometer of the flasks in question. Thereafter the evaluated results from the odometer were used in Chalmersmodellen.
After complementary of the real settlement, where not all measurements exist, the results of our researches showed that Chalmersmodellen with creep were overestimating the settlement before the preconsolidation stress has been reached.
I examensarbetet jämförs verkliga sättningar för den överkonsoliderade leran under Arenahallen i Halmstad med två olika sättningsberäkningsmodeller; Chalmersmodellen utan kryp och Chalmersmodellen med kryp. Chalmersmodellen med kryp grundar sig på Terzaghis konsolideringsekvation med ett tillägg för krypning. Syftet har varit att ta reda på om Chalmersmodellen med kryp kan användas för denna lera eller om Chalmersmodellen utan kryp fungerar bättre. Problemet har lösts genom grundliga litteraturstudier, provtagning av ostörda prover genom kolvprovtagning med geoteknisk borrvagn samt kompressionsförsök med ödometer på tagna kolvar. Därefter utvärderades resultaten från ödometerförsöken och användes i Chalmersmodellen.
Efter komplettering av den verkliga sättningen, där inte all mätdata finns, blev resultatet av våra undersökningar att Chalmersmodellen med kryp överskattar sättningen innan förskonsolideringstrycket är passerat.

Full textGrenrören i en motor utsätts för stora termiska och mekaniska belastningar, vilka gör att grenrören ofta spricker. Idag kan inte sprickbildningen fullständigt uttydas ur beräkningarna, syftet med arbetet är därför att se om dessa kan förbättras genom att använda en mer avancerad krypmodell än den som används idag.
Ett förslag till krypmodell har tagits genom att studera ett antal i litteraturen funna modeller. De som valts ut är modeller enligt Norton, Bailey-Norton, Marin-Pao, Picket och Findley. Parametrarna i de olika modellerna har bestämts genom kurvanpassning av enaxliga prov på de aktuella grenrörsmaterialen. Resultaten visar att modellerna enligt Marin-Pao, Picket och Findley alla kan beskriva mätkurvorna nästan exakt. Problem uppstår dock med att man får parametrar som beror av både spänning och temperatur. Av dessa tre modeller anses Marin-Pao vara den bästa, då det är den av de tre som har minst antal parametrar. Utvärderingen ger vidare att Norton är den modell som är enklast, och beaktat över alla prover, den vars resultat bäst ansluter sig till mätdata. Valet görs att gå vidare med både Marin-Paos och Nortons modell.
De två aktuella modellerna har lagts in som subrutiner till FE-programmet ABAQUS. Tester av modellerna görs först på ett litet kubiskt element och sedan på hela grenröret. Jämförelser görs mellan Norton, Marin-Pao och den modell som används idag – ”Two-layer viscoplasticity model”. Såväl Marin-Paos modell som Nortons beskriver verkligheten bättre än den idag använda modellen och av de båda är Nortons modell den som mest tillfredställande speglar verkligheten. Det är dessutom den modell som är mest stabil och beräkningsmässigt effektivast. Som en rekommendation inför fortsatt arbete föreslås därför användning av Nortons modell, samt ett utökat antal krypprover.
