  1. 6. Cotranslational protein biogenesis in Escherichia coli monitored by force profile analysis

    Författare :Felix Nicolaus; Gunnar von Heijne; Ross Dalbey; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; cotranslational protein biogenesis; membrane protein; soluble protein; transmembrane helices; force profile analysis; arrest peptide; biokemi; Biochemistry;

    Sammanfattning : Proteins are a diverse class of biomolecules that carry out many essential functions across all organisms. They can either be found in aqueous compartments or embedded in biological membranes of the cell and are called soluble or membrane proteins, respectively. LÄS MER

  3. 7. NMR diffusion studies on lyotropic liquid crystalline systems

    Författare :Greger Orädd; Frank Volke; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diffusion; pulsed field gradient; liquid crystalline systems; lipid lateral diffusion; cubic phases; peptide-lipid interactions; hydrophobic mismatch; permeability;

    Sammanfattning : The pulsed field gradient fourier transform nuclear magnetic resonance (PFG-FTNMR) method to measure translational diffusion coefficients in multicomponent systems has been applied to amphiphilic molecules forming liquid crystalline phases.By analyzing the concentration dependence of the diffusion coefficients of water and amphiphile in a micellar system of N,N-dimethyldodecy lamine oxide (DDAO) in water it was possible to conclude that the micelles formed were polydisperse in size and shape.

  4. 8. Lipid production from lignocellulosic material by oleaginous yeasts

    Författare :Jule Brandenburg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Oleaginous yeasts are a potential lipid source for production of fuels, chemicals and food or feed and use of lignocellulosic biomass as feedstock is considered a sustainable approach. Pre-treatment of lignocellulose is required to release the major carbon sources, glucose, xylose and other sugars for lipid production by oleaginous yeasts, but also releases inhibitory compounds.

  5. 9. Bax and oxidized phospholipids - a deadly complex : Apoptotic protein-lipid assemblies studied by MAS NMR spectroscopy

    Författare :Artur Dingeldein; Gerhard Gröbner; Mikael Elofsson; Tobias Sparrman; Daniel Topgaard; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; mitochondrial membranes; apoptosis; membrane dynamics and organization; Bcl-2 family proteins; Bax protein; biokemi; Biochemistry;

    Sammanfattning : Mitochondria are renowned for their vital role as cellular powerhouses because they provide ATP via cellular respiration. Additionally, these organelles also play an important role in other physiological processes, such as apoptosis. LÄS MER

  7. 10. Influence of strain, feed profile and cultivation technique on the lipid structure and membrane function in Escherichia coli

    Författare :Atefeh Shokri; KTH; []
    Nyckelord :Escherichia coli; phospholipid and fatty acid regulation. fed-batch; continuous cultivation; leakage; protein transport;

    Sammanfattning : The phospholipid and fatty acids content of the Escherichiacoli membrane were investigated during changes of feed rate,cultivation technique and host strains.During continuous cultivation it was shown that the leakageof periplasmic protein to the medium had an optimum at 0.3 h-1,resulting in transport of 20% of the total recombinant product.
