  1. 11. Structural and functional studies of the ribosomes : a closer look at expansion segments and translational dynamics in eukaryotes

    Författare :Sofia L. Larsson; Alexei A. Bogdanov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosomer; Zoological Cell Biology; zoologisk cellbiologi;

    Sammanfattning : The ribosome is the basic machinery for protein synthesis in all living cells. In the last decade, there has been an explosion of structural information on the ribosome. The eukaryotic ribosome is larger than the prokaryotic counterpart and contains several extra features, even though they have similar core structures. LÄS MER

  2. 12. The eukaryotic ribosome in focus : a chemical footprinting analysis of ribosome-ligand interactions in in vivo assembled complexes

    Författare :Marika Salonen Sloma; Diarmaid Hughes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi; Zoological Cell Biology; zoologisk cellbiologi;

    Sammanfattning : Protein synthesis is an essential biological process that occurs on ribosomes. The process requires an involvement of numerous components like mRNA, tRNA and translation factors. The mammalian 80S ribosome, the focus of this thesis, is composed of four rRNAs and approximately 80 proteins distributed in two subunits the 40S and 60S subunit. LÄS MER

  3. 13. Genomics and metabolomics in the North Atlantic deep-sea sponge Geodia barretti

    Författare :Karin Steffen; Paco Cárdenas; Ulf Göransson; Anders Backlund; Susanna López-Legentil; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; demosponge; whole genome sequencing; population genetics; peptide synthesis; Farmakognosi; Pharmacognosy;

    Sammanfattning : Sponges are among the earliest diverging taxa in the animal tree of life. They are sessile, filter-feeding animals found in marine and freshwater habitats. Many species are characterized by a close, specific and consistent association with microbes, mainly Bacteria and Archaea. LÄS MER

  4. 14. The Arabidopsis 14-3-3 family -target protein specificity and expression of isoforms

    Författare :Annika Arkell; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein-protein interaction; GUS; Arabidopsis; 14-3-3; H -ATPase; expression;

    Sammanfattning : 14-3-3 proteins comprise a family of highly conserved proteins. 14-3-3 proteins have been found in all organisms examined except for members of the prokaryotic kingdom. 14-3-3s are involved in numerous processes in the cell and they typically bind to phosphorylated motifs in other proteins and regulate their activities.

  5. 15. Creation of new proteins - domain rearrangements and tandem duplications

    Författare :Åsa Björklund; Arne Elofsson; Sarah Teichmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinformatics; Bioinformatik; Biochemistry; biokemi;

    Sammanfattning : Proteins are modular entities with domains as their building blocks. The domains are recurrent protein fragments with a distinct structure, function and evolutionary history. During evolution, proteins with new functions have been invented through rearrangements as well as differentiation of domains. LÄS MER
