  2. 6. DNA and RNA base analogue FRET - from fluorophore design to biochemical applications

    Author : Moa Sandberg Wranne; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; adenine analogue; Fluorescent base analogue; FRET; thymine analogue; netropsin; fluorescence; DNA; RNA; Z-RNA;

    Abstract : This thesis focuses on the development and use of fluorescent base analogues (FBAs). They are important tools in research concerning nucleic acids structure, dynamics and interactions. READ MORE

  4. 7. Functional characterization of the small antisense RNA MicA in Escherichia coli

    Author : Klas Ifeanyi Udekwu; Gerhart Wagner; Tony Romeo; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small RNA; antisense; outer membrane; Hfq-dependence; RNase III; LuxS; Quorum sensing; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : The Escherichia coli small RNA (sRNA) MicA was identified recently in a genomewide search for sRNAs. It is encoded between the genes gshA and luxS in E. coli and its close relatives. The function of sRNAs in bacteria is generally believed to be in maintenance of homeostasis via stress-induced modulation of gene expression. READ MORE

  5. 8. Conformationally Constrained Oligonucleotides for RNA Targeting

    Author : Qing Li; Jyoti Chattopadhyaya; Li-He Zhang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conformationally constrained nucleoside; antisense oligonucleotide; RNA affinity; nuclease stability; RNase H; RNA degradation; Chemistry with specialization in Bioorganic Chemistry; Kemi med inriktning mot bioorganisk kemi;

    Abstract : A short oligonucleotide sequence as in a single-stranded antisense oligo nucleotides (AON) or in double-stranded small interfering RNAs (siRNA) can modulate the gene expression by targeting against the cellular mRNA, which can be potentially exploited for therapeutic purposes in the treatment of different diseases. In order to improve the efficacy of oligonucleotide-based drugs, the problem of target affinity, nuclease stability and delivery needs to be addressed. READ MORE

  6. 9. On Transcriptome Sequencing

    Author : Daniel Klevebring; Joakim Lundeberg; Ulf Gyllensten; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transcriptome; RNA-seq; DNA sequencing; gene expression profiling; non-coding RNA; small RNA; Functional genomics; Funktionsgenomik; Bioinformatics; Bioinformatik; Genetics; Genetik; Molecular biology; Molekylärbiologi; Cell biology; Cellbiologi;

    Abstract : This thesis is about the use of massive DNA sequencing to investigate the transcriptome. During recent decades, several studies have made it clear that the transcriptome comprises a more complex set of biochemical machinery than was previously believed. READ MORE

  7. 10. Ribosomal RNA Modification Enzymes : Structural and functional studies of two methyltransferases for 23S rRNA modification in Escherichia coli

    Author : Avinash S. Punekar; Maria Selmer; Martino Bolognesi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; ribosome biogenesis; ribosome assembly; ribosomal RNA; peptidyltransferase center; domain V; post-transcriptional modification; methyltransferases; S-adenosyl-methionine; RlmM; Cm2498; RlmJ; m6A2030; X-ray crystallography; substrate recognition; substrate specificity; catalytic mechanism; evolution; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi; Biokemi; Biochemistry;

    Abstract : Escherichia coli ribosomal RNA (rRNA) is post-transcriptionally modified by site-specific enzymes. The role of most modifications is not known and little is known about how these enzymes recognize their target substrates. READ MORE
