  1. 1. Evasion and Attack: Structural Studies of a Bacterial Albumin-binding Protein and of a Cephalosporin Biosynthetic Enzyme

    Författare :Sara Lejon; Janos Hajdu; Karin Valegård; Martin Noble; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; human serum albumin; GA module; albumin-binding; Finegoldia magna; deacetylcephalosporin C acetyltransferase; cephalosporin C; antibiotic; beta-lactam; biosynthesis; Acremonium chrysogenum; X-ray crystallography; Structural biology; Strukturbiologi;

    Sammanfattning : This thesis describes the crystal structures of two proteins in the context of combatting bacterial infections. The GA module is a bacterial albumin-binding domain from a surface protein expressed by pathogenic strains of the human commensal bacterium Finegoldia magna. LÄS MER

  3. 2. Studies of genes involved in regulating flowering time in Arabidopsis

    Författare :Maria Svensson; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; flowering time; fold recognition; GA biosynthesis; promoter trapping; RNA-binding; T-DNA tagging; Biology; Biologi; Naturvetenskap; Natural sciences;

    Sammanfattning : Transition from a vegetative growth phase to flowering in plants occurs in response to both environmental conditions and endogenous signals. Identification of genes that are involved in regulating the time of flowering is of great importance in agri- and horticulture. LÄS MER

  4. 3. A genetic approach to the identification of new components regulating development in Arabidopsis thaliana

    Författare :Ingela Fridborg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk botanik; Physiological Botany;

    Sammanfattning : Two new genes involved in important processes of plant development were identified in the model plant Arabidopsis thaliana. The genes were isolated from mutants generated through insertional mutagenesis based on a transposon tagging approach. LÄS MER

  5. 4. Discovery of fiber-active enzymes in Populus wood

    Författare :Henrik Aspeborg; KTH; []
    Nyckelord :Populus; xylogenesis; secondary cell wall; cellulose; hemicellulose; microarrays; transcript profiling; carbohydrate-active enzyme; glycosyltransferase; glycoside hydrolase;

    Sammanfattning : Renewable fibers produced by forest trees provide excellentraw material of high economic value for industrialapplications. Despite this, the genes and corresponding enzymesinvolved in wood fiber biosynthesis in trees are poorlycharacterized. LÄS MER

  7. 5. Vitamin B6 as a potential antioxidant : a study emanating from UV-B-stressed plants

    Författare :Mikael Ristilä; Åke Strid; Leif Eriksson; Éva Hideg; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; UV-B irradiation; pyridoxine; vitamin B6; ROS; Chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : Increased influx of solar UV-B radiation (280-320 nm), due to a decreasing stratospheric ozone layer, impacts severely on plants. Some of the UV-B effects on plants are related to stress induced by produced reactive oxygen species (ROS). Pyridoxine (vitamin B6) has been reported to be a potential quencher of ROS. LÄS MER
