  1. 1. Structural Information and Hidden Markov Models for Biological Sequence Analysis

    Författare :Jeanette Tångrot; Bo Kågström; Uwe H. Sauer; Erik Sonnhammer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HMM; structure alignment; protein structure; secondary structure; remote homologue; annotation; domain family; protein family; protein superfamily; protein fold recognition; Bioinformatics; Bioinformatik;

    Sammanfattning : Bioinformatics is a fast-developing field, which makes use of computational methods to analyse and structure biological data. An important branch of bioinformatics is structure and function prediction of proteins, which is often based on finding relationships to already characterized proteins. LÄS MER

  3. 2. The use of structural information to improve biological sequence similarity searches

    Författare :Jeanette Tångrot; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinformatik; Hidden Markov Model; HMM; protein structure alignment; protein structure superimposition; remote homologue; FISH-server; protein annotation; Bioinformatics; Bioinformatik;

    Sammanfattning : Bioinformatics is a fast-developing field that make use of computational methods to analyse and structure biological data. An important branch of bioinformatics is structure and function prediction of proteins. To determine the structure of a protein is a crucial part in the characterisation of the molecule. LÄS MER

    Författare :Olof Modén; Bengt Mannervik; Mikael Widersten; Kenneth Tew; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; allelic variants; azathioprine; bioactivation; chimeric mutagenesis; directed evolution; DNA shuffling; enzyme engineering; glutathione transferase; GST; lysate screening; molecular docking; multiple alignment; multivariate analysis; polymorphism; principal component analysis; prodrug; prodrug activation; protein engineering; protein redesign; reduced amino acid alphabet; saturation mutagenesis; semi-rational enzyme engineering; site-directed mutagenesis; structure-activity relationship; structure-based redesign; Biokemi; Biochemistry;

    Sammanfattning : Glutathione transferase (GST) A2-2 is the human enzyme most efficient in catalyzing azathioprine activation. Structure-function relationships were sought explaining the higher catalytic efficiency compared to other alpha class GSTs. LÄS MER

  5. 4. Protein structure dynamics and interplay : by single-particle electron microscopy

    Författare :Hans Elmlund; Hans Hebert; José Maria Carazo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biophysics; biochemistry; molecular; Biophysical chemistry; Biofysikalisk kemi;

    Sammanfattning : Single-particle cryo-electron microscopy (cryo-EM) is a method capable of obtaining information about the structural organization and dynamics of large macromolecular assemblies. In the late nineties, the method was suggested to have the potential of generating “atomic resolution” reconstructions of particles above a certain mass. LÄS MER

  7. 5. New methods for protein structure threading and domain identification

    Författare :Mats Lindstam; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biomatematik; Molecular biophysics; Molekylär biofysik; medicinsk informatik; Bioinformatik; biomathematics biometrics; medical informatics; structure prediction; Bioinformatics; domain identification; Structural bioinformatics; threading;

    Sammanfattning : The availability of three-dimensional structures of proteins has provided enormous insight into the detailed molecular machinery of the living cell. Since the late 1950s and early 1960s, experimental methods for deriving protein structures have contributed more than 30,000 entries to the Protein Data Bank, representing the collected knowledge of protein and other macromolecular structures.
