  1. 16. Structural and functional basis of mitochondrial tRNA processing

    Författare :Sagar Sridhara; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The mammalian mitochondria are subcellular organelles, generating energy in the cell by the synthesis of adenosine triphosphate (ATP) via oxidative phosphorylation (OXPHOS). The maintenance of proper mitochondrial (mt) structure and function requires more than 1000 proteins generated from the nuclear DNA (nDNA) expression and 13 protein subunits generated from the mitochondrial DNA (mtDNA) expression.

  3. 17. Theoretical prediction of ionisation properties of proteins

    Författare :Assen Koumanov; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This work emphasises on elaboration of improved theoretical and computational methods for determination of protonation/deprotonation equilibria in proteins. It also aims to contribute for a better understanding on atomic level of ionisation properties of proteins and their role in structure-functional relationship. LÄS MER

  4. 18. Studies on cytokines in experimental metal-induced systemic autoimmunity

    Författare :Bo Häggqvist; Nils-Gunnar Ilbäck; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The effect on the imnnme system of inorganic mercury (Hg), organic mercury (methyl mercury-MeHg), and silver was examined in mouse strains genetically susceptible or resistant to metal-induced systemic autoimmunity (MIA). The major aim was to study the cytokine mRNA expression in the immune system of metal-treated mice, and relate these findings to the different parameters of MIA. LÄS MER

  5. 19. Molecular detection of abundance and activity of marine, symbiotic, N2-fixing cyanobacteria

    Författare :Linnéa Ström; Rachel Foster; Daniel Lundin; Katharina Pawlowski; Rehab El-Shehawy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diatom Diazotroph Association; Richelia; Iron; Phosphorus; Nitrogen; nifH; pstS; exbB; rnpA; växtfysiologi; Plant Physiology; marinbiologi; Marine Biology;

    Sammanfattning : Marine primary productivity in large parts of the oceans is supported by nitrogen fixers (diazotrophs). Richelia, a genus of multiple closely related species of heterocystous filamentous cyanobacterial diazotrophs, are often found in symbioses with a few genera of diatoms. Several Richelia species: R. euintracellularis, R. LÄS MER

  7. 20. Analysis of noncovalent and covalent protein-ligand complexes by electrospray ionisation mass spectrometry

    Författare :Gustav Sundqvist; Harry Brumer; Per Andrén; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; noncovalent complex; droplet fission; nano-electrospray ionisation; mass spectrometry; Analytical chemistry; Analytisk kemi;

    Sammanfattning : In this thesis, the application of electrospray ionisation mass spectrometry (ESI-MS) to the analysis of intact proteins is demonstrated. In papers I and II, the use of ESI-MS for the analysis of noncovalent protein-ligand complexes were discussed. LÄS MER
