  1. 1. Characterization of the DNA-Binding Properties of the Cyanobacterial Transcription Factor NtcA

    Author : Susanne Wisén; Bengt Mannervik; Enrique Flores; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; NtcA; transcription regulation; cyanobacteria; redox regulation; DNA binding; nitrogen fixation; Anabaena PCC 7120; Biokemi; Biochemistry; Biokemi;

    Abstract : Nitrogen is an essential building block of proteins and nucleic acids and, therefore, crucial for the biosphere. Nearly 79 % of the air consists of nitrogen, but in the form of nitrogen gas (N2), which cannot be utilized by most organisms. READ MORE

  2. 2. Unveiling biomacromolecule interactions-NMR and optical spectroscopy studies on ligand binding to DNA and lysozyme

    Author : Lisha Wu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ruthenium compounds; intercalation; Hoechst 33258; CD; fluorescence; DNA; structure rearrangements.; lysozyme; NMR;

    Abstract : Studies on intercalation of bulky binuclear ruthenium compounds into DNA have attracted attention due to their slow dissociation rate and sequence selectivity. Previous results showed that dumb-bell shaped molecules of the type [μ-(bidppz)(L)4Ru2]4+, L=phenanthroline or bipyridine, bind rapidly on the surface of DNA prior to intercalation. READ MORE

  3. 3. DNA precursor biosynthesis-allosteric regulation and medical applications

    Author : Reza Rofougaran; Anders Hofer; Thomas Borén; Staffan Eriksson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; DNA biosynthesis; ribonucleotide reductase; allosteric regulation; Trypanosoma brucei; adenosine kinase; nucleoside analogs; mitochondrial DNA; TWINKLE; Biokemi; medicinsk biokemi; Medical Biochemistry;

    Abstract : Ribonucleotide reductase (RNR) is a key enzyme for de novo dNTP biosynthesis. We have studied nucleotide-dependent oligomerization of the allosterically regulated mammalian RNR using a mass spectrometry–related technique called Gas-phase Electrophoretic Mobility Macromolecule Analysis (GEMMA).

  4. 4. Functional Studies of Telomere-Binding Proteins in Saccharomyces castellii

    Author : Jenny Rhodin; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rap1; DNA-binding domain; telomere evolution; Cdc13; telomerase; single-stranded overhang; telomere; yeast; Naumovia castellii; Saccharomyces castellii;

    Abstract : Telomeres are the ends of linear eukaryotic chromosomes. The telomeres are essential for solving the end replication problem and they stabilize the genome by protection from degradation. The telomeres also protect the chromosomal ends from by being recognized as DNA breaks by the repair machinery, which could lead to end-to-end fusions. READ MORE

  5. 5. DNA and protein interactions of mouse polyomavirus large T antigen

    Author : Ola Rönn; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; T-antigen; DNA-binding; biosensor; enhancer; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Abstract : Polyomaviruses require dividing cells to multiply. The regulatory genes express proteins, theT-antigens, necessary for this to occur. Large T-antigen (LT), is a phosphoprotein withmultiple intrinsic activities, e.g. READ MORE
