  1. 1. Studies on the Role of UDP-Glucose Dehydrogenase in Polysaccharide Biosynthesis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Elisabet Roman; Uppsala universitet.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; UDP-glucose dehydrogenase; polysaccharide biosynthesis; glycosaminoglycan; A. thaliana; E. coli K5; Biokemi; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : Polysaccharides are found in all forms of life and serve diverse purposes. They are enzymatically synthesised from activated monosaccharide precursors, nucleotide sugars. One such nucleotide sugar is UDP-glucuronic acid, which is formed from UDP-glucose by the UDP-glucose dehydrogenase (UGDH) enzyme. LÄS MER

  2. 2. Cellulose Biosynthesis in Oomycetes

    Detta är en avhandling från Stockholm : KTH

    Författare :Johanna Fugelstad; Vincent Bulone; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose biosynthesis; cellulose synthase genes; Oomycetes; Phytophthora infestans; Saprolegnia monoica.; TECHNOLOGY Bioengineering Other bioengineering; TEKNIKVETENSKAP Bioteknik Övrig bioteknik;

    Sammanfattning : Oomycetes have long been considered as a separate class within the kingdom Fungi, but they are in fact closer to brown algae. They are currently classified in the Stramenopile eukaryotic kingdom, which includes heterokont algae and water molds. LÄS MER

  3. 3. Heparan Sulfate Biosynthesis – Clues from Knockout Mice

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Johan Ledin; Lena Kjellén; John Gallagher; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; heparan sulfate; biosynthesis; gene targeting; embryonic development; proteoglycans; NDST; N-deacetylase N-sulfotransferase; Cell- och molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi;

    Sammanfattning : In the extracellular space, many specialized proteins are located to support cells and to mediate cell-cell signalling. One class of such molecules is heparan sulfate (HS) proteoglycans, which are proteins with different properties and locations but all of them decorated with long unbranched HS polysaccharide chains.

  4. 4. Functions of Heparan Sulfate During Mouse Development Studies of Mice with Genetically Altered Heparan Sulfate Biosynthesis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Ringvall; Lena Kjellén; Erik Forsberg; Ulf Lindahl; Erika Gustafsson; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; embryonic development; gene targeting; lung development; ossification; heparan sulfate; heparin; N-deacetylase N-sulfaotransferase; NDST; proteoglycan; morphogen; biosynthesis; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi;

    Sammanfattning : Heparan sulfate (HS) is a ubiquitous polysaccharide on the cell surface and in the extracellular matrix. HS is an important actor in the regulation of cell signaling, especially in the developing embryo. LÄS MER

  5. 5. Enzymes involved in biosynthesis and degradation of heparin-related polysaccharides

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Dagmar Sandbäck Pikas; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparin; heparan sulphate; biosynthesis; N-deacetylase N-sulphotransferase; endoglycosidase; heparanase; Biokemi; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : Heparin and heparan sulphate (HS) are structurally related polysaccharides of the glycosaminoglycan type. As the glycan moiety of proteoglycans, they exist covalently linked to various core proteins. LÄS MER
