  1. 16. Molecular Phylogenetics of Mammals

    Författare :Morgan Kullberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; EST; divergence times; phylogenomics; phylogenetic reconstruction; Mammals; Eutheria; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : In this thesis, the phylogenetic relationships of the Mammalia have been studied at various levels. Different sources of genetic information have been evaluated and used as phylogenetic markers. These include the well-known mitochondrial genome, cDNA from housekeeping genes and expressed sequence tags from nuclear genes. LÄS MER

  3. 17. Towards Classification and Functional Description of Enzymes: A case study of feruloyl esterases

    Författare :Gupta Udatha; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; descriptors; enzyme immobilization; catalytic triad; pharmacophore; enzyme promiscuity; functional classification; molecular docking; feruloyl esterases; protein evolution; structure-function relationship;

    Sammanfattning : The prediction of enzyme functionality from sequence or structure data remains a challenging task that can be best addressed by studying the structure-function relationships determined from previously available information. This thesis work was focused on developing a reliable classification and functional description for the feruloyl esterase (FAE) enzyme family, whose members’ possess both structural and catalytic promiscuity.

  4. 18. Transcription regulation across levels of chromatin organization

    Författare :Roshan Vaid; Mattias Mannervik; Goncalo Castelo-Branco; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transcription; chromatin; epigenetics; Drosophila; embryo development; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : With advancements in high-throughput sequencing and high-resolution microscopy techniques, the significance of genome organization in transcription regulation is rapidly unveiling. Nonetheless, we are yet far from completely understanding this key relationship. LÄS MER

  5. 19. Engineering membrane proteins for production and topology

    Författare :Stephen Toddo; Daniel Daley; Roslyn Bill; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane protein; Over-expression; Protein production; Codon optimization; Escherichia coli; AraH; NarK; mRNA secondary structure; coding sequence; ribosome binding site; RBS; topology; split-GFP; Biochemistry; biokemi;

    Sammanfattning : The genomes of diverse organisms are predicted to contain 20 – 30% membrane protein encoding genes and more than half of all therapeutics target membrane proteins. However, only 2% of crystal structures deposited in the protein data bank represent integral membrane proteins. LÄS MER

  7. 20. A-to-I RNA editing : Function and consequences during brain development

    Författare :Ylva Ekdahl; Marie Öhman; Kazuko Nishikura; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNA editing; miRNAs; Brain development; Molecular Biology; molekylärbiologi;

    Sammanfattning : The aim of my thesis has been to study how A-to-I RNA editing of miRNAs is regulated during brain development and the biological function of these editing events.Using high throughput RNA sequencing, we performed an unbiased search for edited, mature miRNAs in total mouse brain tissue from three developmental stages.
