  1. 1. Nucleotide Binding to Trimeric dUTPase: Studies on Recombinant Enzymes using Kinetic and Spectroscopic Methods

    Författare :Johan Nord; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C-terminus; dUTPase; EIAV; Escherichia coli; flexibility; Homo sapiens; kinetics; NMR; nucleotide metabolism; rate constants of lig-and binding; production of recombinant enzyme; dUTP; specificity; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : Recombinant dUTPase from the bacterium Escherichia coli, the retrovirus equine infectious anemia virus (EIAV) and Homo sapiens have been made available for physico-chemical characterisation. The protocols developed have also proven to be suitable for production of enzymes modified by isotope labelling or other methods. LÄS MER

  3. 2. Exploring the steroidogenic activity of glutathione transferases across species

    Författare :Helena Lindström; Bengt Mannervik; Kjell Wikvall; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glutathione transferase; steroidogenesis; GST A3-3; testis; androstenedione; pregnenedione; equine; steroidogenesis inhibition; Drosophila GSTE14; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Glutathione transferases (GSTs) comprise a superfamily of enzymes prominently involved in detoxication. However, some GSTs have developed alternative functions. LÄS MER

  4. 3. Equine glutathione transferase A3-3 : an efficient steroid isomerase

    Författare :Helena Lindström; Bengt Mannervik; Ann-Kristin Östlund Farrants; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Equine; glutatione transferase; steroidogenesis; steroid isomerase; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Glutathione transferases (GSTs) comprise a superfamily of enzymes prominently involved in detoxication by making toxic electrophiles more polar and therefore more easily excretable. However some GSTs have developed alternative functions. LÄS MER

  5. 4. Computational Approaches to the Identification and Characterization of Non-Coding RNA Genes

    Författare :Pontus Larsson; Anders Virtanen; Leif Kirsebom; Stephen Mount; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ncRNA; snRNA; U1; splice site; alternative splicing; Dictyostelium; nucleotide composition; partial sums; Bioinformatics; Bioinformatik;

    Sammanfattning : Non-coding RNAs (ncRNAs) have emerged as highly diverse and powerful key players in the cell, the range of capabilities spanning from catalyzing essential processes in all living organisms, e.g. protein synthesis, to being highly specific regulators of gene expression. LÄS MER

  7. 5. Kognitiv utveckling och låtsaslekens mysterier

    Författare :Mikael Jensen; Högskolan i Borås; []
    Nyckelord :kognition; låtsaslek; lärande; Humaniora med inriktning mot lärarprofessionen;

    Sammanfattning : What kind of cognitive capacity must a human child develop to be able to join pretend play? This is the main question of the dissertation. To get a fair answer a great part of the background discusses what pretend play and human cognition is. Homo sapiens sapiens seems to be the only now living animal that is capable of pretense. LÄS MER
