  1. 16. Membrane Protein Biogenesis in Escherichia coli : A proteomics approach

    Författare :David Vikström; Jan-Willem de Gier; Eitan Bibi; Stockholms universitet; []
    Nyckelord :SRP; YidC; SecE; Membrane protein biogenesis; protein targeting; 2D BN SDS-PAGE; Biochemistry; biokemi;

    Sammanfattning : In the bacterium Escherichia coli all proteins are synthesized in the cytoplasm. However, at least 25% of them then need to be exported to another cellular compartment where they exert their function. E. coli has several different targeting pathways to ensure the correct localization of its proteins. LÄS MER

  3. 17. CPSRP54 and co-translational targeting of chloroplast encoded thylakoid membrane proteins

    Författare :Robert Nilsson; Ralph Henry; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Chloroplasts are essential organelles of prokaryotic origin that are present in green tissue of higher plants and algae. Chloroplasts are predicted to contain ~3000 proteins and the vast majority of these proteins are encoded by nuclear genes. Chloroplasts also have a small circular genome encoding 100-120 tRNAs, rRNAs and proteins. LÄS MER

  4. 18. The Development of Swedish Business Journalism : Historical Roots of an Organisational Field

    Författare :Maria Grafström; Kerstin Sahlin-Andersson; Lars Engwall; Stefan Jonsson; Royston Greenwood; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; institutional theory; organisational field; field emergence; institutional entrepreneurs; business journalism; business news; newspapers; Företagsekonomi;

    Sammanfattning : Contemporary Swedish business journalism is an established organisational field with shared practice within and across organisations. Using a historical perspective, this dissertation investigates the early formation of this field and the formation of a shared meaning system for business journalism. LÄS MER

  5. 19. Characterization of RNA exosome in Insect Cells : Role in mRNA Surveillance

    Författare :Viktoria Hessle; Neus Visa; Maria Carmo-Fonseca; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell nucleus; nuclear bodies; mRNA surveillance; cotranscriptional assembly; Rrp6; Rrp4; mRNP; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : The exosome, an evolutionarily conserved protein complex with exoribonucleolytic activity, is one of the key players in mRNA quality control. Little is known about the functions of the exosome in metazoans. We have studied the role of the exosome in nuclear mRNA surveillance using Chironomus tentans and Drosophila melanogaster as model systems. LÄS MER

  7. 20. Laser-Induced Incandescence and Complementary Diagnostics for Flame Soot Characterization

    Författare :Nils-Erik Olofsson; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2015:Olofsson;

    Sammanfattning : This work has been aimed at developing and applying laser-induced incandescence (LII) for flame soot characterization. The basic principle of LII is rapid heating of the soot particles to temperatures of 3500-4000 K by short laser pulses. Thereby the intensity of the soot incandescence is increased. LÄS MER
