  1. 1. Pathogenecity-associated genes modulate Escherichia coli adhesion and motility

    University dissertation from Umeå : Molekylärbiologi

    Author : Annika E. Sjöström; Umeå universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Escherichia coli strains typical of UPEC (uropathogenic E. coli) and NBM (newborn meningitis) isolates carry chromosomally located PAIs (pathogenicity islands) that are absent in non-pathogenic E. coli strains. The PAIs include genes for virulence factors such as toxins and genes coding for specific adhesins and pili/fimbriae formation. READ MORE

  2. 2. Small Molecules as Tools in Biological Chemistry Effects of Synthetic and Natural Products on the Type III Secretion System

    University dissertation from Umeå : Umeå universitet

    Author : Caroline E. Zetterström; Umeå universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Type III secretion; salicylidene acylhydrazide; virulence-blocker; virulence; inhibitor; target identification; neohopeaphenol A; Yersinia pseudotuberculosis; Pseudomonas aeruginosa; Escherichia coli; biologisk kemi; biological chemistry;

    Abstract : The increasing use of antibiotics has led to a huge problem for society, as some bacteria have developed resistance towards many of the antibiotics currently available. To help find solutions to this problem we studied small molecules that inhibit bacterial virulence, the ability to cause disease. READ MORE

  3. 3. Identification and functional characterization of novel thioredoxin systems

    University dissertation from Stockholm : Karolinska Institutet, Biosciences and Nutrition

    Author : Anastasios E Damdimopoulos; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antioxidants; Reactive Oxygen Species; Tbioredoxin; Tbioredoxin Reductase;

    Abstract : Thioredoxins (Trx) are a class of small multifunctional 12-kDa proteins that are characterized by the redox active site Trp-Cys-Gly-Pro-Cys (WCGPC). In the oxidized (inactive) form of Trx (Trx-S2), the two cysteines at the active site form a disulfide bond. READ MORE

  4. 4. Protein production in the E. coli cell envelope

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Thomas Baumgarten; Jan-Willem de Gier; Dirk-Jan Scheffers; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; E. coli; protein biogenesis; recombinant proteins; membrane proteins; secretory proteins; protein displays; outer membrane vesicles; biokemi; Biochemistry;

    Abstract : Proteins fulfil essential functions in every cell and malfunctioning proteins are often the cause of diseases. On the other hand, proteins like antibody fragments or hormones can be used to treat diseases. READ MORE

  5. 5. Molecular analysis of transcription factors in uropathogenic E. coli adhesin operons

    University dissertation from Umeå : Umeå Universitet

    Author : Stina Lindberg; Umeå universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; UPEC; E. coli; F1C; P fimbriae; cross-talk; FocB; PapB; crystal structure; OMVs; MEDICINE Microbiology; immunology; infectious diseases Microbiology Medical microbiology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Mikrobiologi Medicinsk mikrobiologi; molekylärbiologi; Molecular Biology;

    Abstract : The main causative agent of human urinary tract infections is the uropathogenic Escherichia coli (UPEC) pathotype. It may cause disease due to its ability to express a number of bacterial virulence factors. Fimbrial adhesins are particularly important for the initial establishment of infection in the urinary tract. READ MORE
