    Sammanfattning : The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals with this ability. LÄS MER

  3. 38. Enzymes in the Mycobacterium tuberculosis MEP and CoA Pathways Targeted for Structure-Based Drug Design

    Författare :Christofer Björkelid; T. Alwyn Jones; Torsten Unge; Sherry L. Mowbray; William N. Hunter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tuberculosis; Mycobacterium tuberculosis; MEP pathway; CoA pathway; drug development; crystal structure; DXR; IspD; PanK; Biokemi; Biochemistry; Molecular Biology; Molekylärbiologi;

    Sammanfattning : Tuberculosis, caused by the pathogenic bacteria Mycobacterium tuberculosis, is one of the most widespread and deadly infectious diseases today. Treatment of tuberculosis relies on antibiotics that were developed more than 50 years ago. These are now becoming ineffective due to the emergence of antibiotic resistant strains of the bacteria.

  4. 39. Thiopurine S-methyltransferase - characterization of variants and ligand binding

    Författare :Annica Blissing; Lars-Göran Mårtensson; Tomas Nyman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Thiopurine S-methyltransferase TPMT ; protein stability; enzyme kinetics; ligand binding; isothermal titration calorimetry ITC ; 8-anilinonaphthalene-1-sulfonic acid ANS ;

    Sammanfattning : Thiopurine S-methyltransferase (TPMT) belongs to the Class I S-adenosylmethionine-dependent methyltransferase (SAM-MT) super family of structurally related proteins. Common to the members of this large protein family is the catalysis of methylation reactions using S-adenosylmethionine (SAM) as a methyl group donor, although SAM-MTs act on a wide range of different substrates and carry out numerous biologically important functions.

  5. 40. Computational Modelling of Ligand Complexes with G-Protein Coupled Receptors, Ion Channels and Enzymes

    Författare :Lars Boukharta; Johan Åqvist; Christopher A. Reynolds; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; molecular dynamics; ligand binding; free energy perturbation; linear interaction energy; binding free energy; homology modelling; structure prediction; alanine scanning; site-directed mutagenesis; hERG; GPCR; neuropeptide Y; HIV-1 reverse transcriptase; integron integrase; Molecular Biotechnology; Molekylär bioteknik;

    Sammanfattning : Accurate predictions of binding free energies from computer simulations are an invaluable resource for understanding biochemical processes and drug action. The primary aim of the work described in the thesis was to predict and understand ligand binding to several proteins of major pharmaceutical importance using computational methods. LÄS MER
