  1. 16. Protein Structure Prediction : Model Building and Quality Assessment

    Author : Björn Wallner; Arne Elofsson; Michael Levitt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein structure prediction; proteinstrukturförutsägelse; Bioinformatics; Bioinformatik;

    Abstract : Proteins play a crucial roll in all biological processes. The wide range of protein functions is made possible through the many different conformations that the protein chain can adopt. The structure of a protein is extremely important for its function, but to determine the structure of protein experimentally is both difficult and time consuming. READ MORE

  2. 17. Factors Affecting Rates of Change in Soil Bacterial Communities

    Author : Marie Pettersson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Plant ecology; Växtekologi; bacteriology; Microbiology; DGGE; PLFA; TdR-incorporation; function; structure; tolerance; adaptation; pH; soil bacterial community; temperature;

    Abstract : The soil bacterial community is under the constant influence of its environment. Changing any of the factors affecting the bacterial community will induce a selection pressure which, with time, will change the community. In this work the effect of changing the temperature or pH on the soil bacterial community was studied. READ MORE

  3. 18. Glutaredoxins : structure, function and mechanism

    Author : Fredrik Åslund; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Thioredoxin (Trx) and glutaredoxin (Grx) are small (9-12 kDa) intracellular disulfide reducing enzymes. They were originally described as hydrogen donors for ribonucleotide reductase (RR), the enzyme that catalyzes the conversion of ribonucleotides to deoxyribonucleotides. READ MORE

  4. 19. Structural and Functional Studies of Wilms Tumour Protein - WT1; Novel Insights into Functionality of Zinc Finger Proteins

    Author : Elmar Nurmemmedov; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; function; structure; transcription factor; cancer; affinity; kinetics; Biacore; RNA binding; DNA binding; Wilms tumour WT1 ; zinc finger;

    Abstract : The molecular process under which message in DNA is relayed onto RNA is called transcription, and it accomplished through involvement of so-called transcription factors. Zinc finger proteins are one of the most abundant classes of regulatory proteins in eukaryotic cells where they play central roles in a variety of cellular activities. READ MORE

  5. 20. Tripeptidyl-Peptidase II : Structure, Function and Gene Regulation

    Author : Ann-Christin Lindås; Birgitta Tomkinson; Mikael Widersten; Ralf Morgenstern; Uppsala universitet; []
    Keywords : Biochemistry; gene regulation; protein expression; enzyme kinetics; tripeptidyl-peptidase II; proteasome; intracellular protein degradation; exopeptidase; Biokemi;

    Abstract : The protein degradation process is of vital importance for the cell to maintain cellular functions. An important enzyme in this process is the multimeric tripeptidyl-peptidase II (TPP II). It removes tripeptides from a free N-terminus of the substrates. READ MORE
