  2. 1. Plant UDP-glucose Pyrophosphorylase : Function and Regulation

    Author : Meng Meng; Leszek Kleczkowski; Javier Pozueta-Romero; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; UDP-glucose pyrophosphorylase; carbohydrate metabolism; in vivo regulation; T-DNA knockout; heterologous expression; isozyme; mutagenesis; kinetic property; oligomerization; Plant physiology; Växtfysiologi;

    Abstract : UDP-glucose pyrophosphorylase (UGPase) is an important enzyme of carbohydrate metabolism in all living organisms. The main aim of this thesis was to investigate the function and regulation of plant UGP genes as well as the UGPase proteins. READ MORE

  4. 2. Gene regulation of UDP-glucose synthesis and metabolism in plants

    Author : Henrik Johansson; Pierdomenica Perata; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; antisense; Arabidopsis thaliana; carbohydrate; hybrid aspen; photosynthesis; poplar; sugar; UDP-glucose; UDP-glucose pyrophosphorylase; UDP-glucose dehydrogenase; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Photosynthesis captures light from the sun and converts it into carbohydrates, which are utilised by almost all living organisms. The conversion between the different forms of carbohydrates is the basis to form almost all biological molecules. READ MORE

  5. 3. A UDP-glucose deficient mutant cell line as a model to study the cytotoxicity of Clostridium perfringens PLC

    Author : Marietta Flores Diaz; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : A Chinese Hamster fibroblast mutant cell line, deficient in UDP-glucose (UDP-Glc) and hypersensitive to Clostridium perfringens phospholipase C (PLC) was used in this study to determine some of the molecular consequences of a cellular UDP-Glc deficiency. Furthermore, using this cell as a model, structure/function studies were performed to identify residues critical for the cytotoxic activity of PLC. READ MORE

  6. 4. Metabolic Engineering of the Central Carbon Metabolism in Streptococcus thermophilus for Enhanced Exopolysaccharide Production

    Author : Malin Svensson; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; Analytisk kemi; Analytical chemistry; metabolism; Biokemi; Metabolism; mykologi; Biochemistry; virologi; Mikrobiologi; bakteriologi; virology; mycology; bacteriology; Streptococcus thermophilus; Microbiology; Metabolic engineering; Lactic acid bacteria; Exopolysaccharides; Central carbon metabolism;

    Abstract : The lactic acid bacterium, Streptococcus thermophilus, is used in the dairy industry in mixed cultures with Lactobacillus delbrueckii subsp. bulgaricus for the production of yoghurt. Many strains of S. thermophilus produce exopolysaccharides (EPSs) which affect the texture and viscosity of fermented food products. READ MORE

  7. 5. Metabolic Engineering of Disaccharide Catabolism for Polysaccharide Formation in Lactococcus lactis and Streptococcus thermophilus

    Author : Fredrik Levander; Institutionen för immunteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; metabolic engineering; exopolysaccharide; polysaccharide; disaccharide; Streptococcus thermophilus; lactic acid bacteria; Lactococcus lactis; Biochemical technology; Biokemisk teknik; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Exopolysaccharides (EPSs) produced by the lactic acid bacteria (LAB) Lactococcus lactis and Streptococcus thermophilus are important for the rheological behaviour and texture of a variety of fermented food products. Furthermore, EPSs from food-grade LAB have potential as food additives and functional food ingredients with both health and economic benefits. READ MORE
