  1. 1. Insights Into Protein Synthesis - Structural Aspects of Elongation Factor G and Fusidic Acid Inhibition

    University dissertation from Molecular Biophysics, Lund University

    Author : Sebastian Hansson; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molekylär biofysik; Structure chemistry; Strukturkemi; Molecular biophysics; Biologi; Biology; Biomedicinska vetenskaper; Biomedical sciences; conformational change; fusidic acid; protein synthesis; elongation factor G; crystal structures;

    Abstract : Elongation factor G (EF-G) catalyses the translocation step in protein synthesis on the ribosome. During this event the antibiotic Fusidic acid (FA) binds to and irreversably inhibits the release of the EF-G:GDP complex from the ribosome. READ MORE

  2. 2. Iron in Haem Biosynthesis. Structural Studies of Ferrochelatase and Frataxin

    University dissertation from KFS AB

    Author : Tobias Karlberg; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; Molekylär biofysik; Molecular biophysics; Biomedicinska vetenskaper; Biomedical sciences; protein crystallography; ferrochelatase; haem biosynthesis; iron; frataxin;

    Abstract : Ferrochelatase catalyses the synthesis of heme by inserting Fe(II) into protoporphyrin IX. The structure of ferrochelatase from yeast has been determined (2.4 Å). The structure is homodimeric with each of the monomer made up of two Rossmann type domains with an active-site cleft between them. READ MORE

  3. 3. Interactions between Streptococcus pyogenes and the human immune defence

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Maria E Nilsson; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M protein; Streptococcus pyogenes; Streptolysin O; The complement system; Neutrophils; Biomedical sciences; Biomedicinska vetenskaper; General biomedical sciences; Biomedicinska vetenskaper allmänt ; Microbiology; transplantation; Immunology; serology; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; Immunologi; serologi; Infections; Infektioner; Clinical biology; Klinisk biologi; bacteriology;

    Abstract : Streptococcus pyogenes is an important human pathogen frequently colonizing the throat and skin of humans. To facilitate colonization and spread and to avoid the host immune defence, streptococci are endowed with a variety of virulence factors, two of which are investigated in this thesis namely streptolysin O (SLO) and M protein.

  4. 4. Selenium Compounds and Antioxidant Capacity in Bovine Milk. Studies on Glutathione Peroxidase, Bioavailability and Electrochemical Techniques

    University dissertation from Pure and Applied Biochemistry, Lund University

    Author : Jun Chen; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; General biomedical sciences; Biomedicinska vetenskaper allmänt ; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; amperometry; voltammetry; antioxidant capacity; ileostomy; bioavailability; glutathione peroxidase; bovine milk; selenium;

    Abstract : The efficacy and function of antioxidants have been intensively studied in foods and other biological systems in recent decades. This thesis concerns different aspects of the antioxidant properties of bovine milk, with emphasis on measurement of the total antioxidant capacity (TAC), the activity of the selenium-containing glutathione peroxidase (GSHPx), and the bioavailability of selenium from bovine milk in humans.

  5. 5. Bioactive Proteins in Bovine Milk - Studies on Glutathione Peroxidase, Lactoferrin and Immunoglobulins

    University dissertation from Helena Lindmark Månsson, Swedish Dairy Association, Scheelevägen 18, SE-223 63 Lund, Sweden

    Author : Helena Lindmark Månsson; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; General biomedical sciences; Biokemisk teknik; Biochemical technology; thermal stability; milk processability; selenium; antioxidants; immunoglobulin; lactoferrin; Milk; glutathione peroxidase; Biomedicinska vetenskaper allmänt ; Biochemistry; Metabolism; Biokemi; metabolism;

    Abstract : Many proteins in bovine milk exhibit specific biological activity in addition to their established nutritional value as source of protein. Examples of such bioactive proteins are extracellular glutathione peroxidase, lactoferrin and immunoglobulins. READ MORE
