  1. 6. Analysis of large-scale metagenomic data

    Författare :Fredrik Boulund; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metagenomics; DNA analysis; big data; antibiotic resistance; hidden Markov models; high-performance computing; distributed computing; distributed computing;

    Sammanfattning : The topic of this thesis is the analysis of large data sets of DNA sequence data produced from modern high-throughput DNA sequencing machines. Using such machines to sequence the genetic content of a microbial community produces a metagenome. This thesis comprises three research papers, all connected to the study of large metagenomic data sets. LÄS MER

  2. 7. From Sequence to Sorting : Prediction of Signal Peptides

    Författare :Henrik Nielsen; Philipp Bucher; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : In the present age of genome sequencing, a vast number of predicted genes are initially known only by their putative nucleotide sequence. The newly established field of bioinformatics is concerned with the computational prediction of structural and functional properties of genes and the proteins they encode, based on their nucleotide and amino acid sequences.

  3. 8. From Sequence to Structure : Using predicted residue contacts to facilitate template-free protein structure prediction

    Författare :Mirco Michel; Arne Elofsson; Erik Lindahl; Johannes Söding; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein bioinformatics; protein structure prediction; contact prediction; machine learning; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

    Sammanfattning : Despite the fundamental role of experimental protein structure determination, computational methods are of essential importance to bridge the ever growing gap between available protein sequence and structure data. Common structure prediction methods rely on experimental data, which is not available for about half of the known protein families. LÄS MER

  4. 9. Evolution of Interactions Involving Intrinsically Disordered Proteins

    Författare :Emma Åberg; Per Jemth; Madan Babu; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; intrinsically disordered proteins; protein evolution; phylogenetics; ancestral sequence reconstruction; biophysical characterization; NCBD; CID; p53; MDM2; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Biokemi; Biochemistry;

    Sammanfattning : This thesis describes the evolution of intrinsically disordered proteins and their interaction partners. The work presented is a combination of phylogenetic analysis, ancestral reconstruction and biophysical characterization in order to examine the evolutionary trajectory of protein-protein interactions involving disorder.

  5. 10. The deep evolutionary roots of non-coding RNA - a comparative genomics approach

    Författare :Marc Patrick Hoeppner; Anthony M. Poole; Britt-Marie Sjöberg; Jürgen Brosius; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; non-coding RNA; evolution; comparative genomics; RNA world; introns; snoRNA; miRNA; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : Non-coding RNAs (ncRNA) are a diverse group of genes that do not encode proteins but function exclusively on the level of RNA and were originally suggested to be remnants of a pre-DNA stage of life known as the RNA world. More recent work, however, has uncovered a rich repertoire of previously unknown families with possible consequences for our understanding of the origin and evolution of the modern RNA infrastructure.
