  1. 1. 2nd and 3rd generation electrodes for biosensors and biofuel cells

    Författare :MNadeem Zafar; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; WrbA; pyranose dehydrogenase; cellobiose dehydrogenase; glucose dehydrogenase; direct electron transfer; Os-polymers; mediated electron transfer; single-walled carbon nanotubes; amperometric biosensor; biofuel cell; screen-printed electrodes; flow injection analysis; cascade reaction; bioanode;

    Sammanfattning : The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and GDH have a catalytic FAD-containing domains. LÄS MER

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

    Författare :Henrik Johansson; Pierdomenica Perata; Umeå universitet; []

    Sammanfattning : 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. LÄS MER

  4. 3. Cellobiose dehydrogenase on electrodes - an electrochemical biosensor for various analytes tunable by positive charges

    Författare :Christopher Schulz; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellobiose dehydrogenase; direct electron transfer; amperometric biosensor; glucose; lactose; cellobiose; calcium; polycation; graphite; gold; electrode;

    Sammanfattning : Cellobiose dehydrogenase (CDH) is a sugar oxidizing enzyme secreted by various species of wood degrading fungi to assist the process of wood degradation. It can oxidise analytically relevant sugars as cellobiose, lactose or glucose leading to a gain of two electrons per sugar molecule. LÄS MER

  5. 4. Beta-glucose 1-phosphate interconverting enzymes in Lactococcus lactis: physiological role and regulation in maltose, trehalose and glucose metabolism

    Sammanfattning : Lactic acid bacteria (LAB), including Lactococcus lactis, are abundant in nature. These bacteria convert carbohydrates into mainly lactate by a rather uncomplicated metabolism. An improved understanding of the physiological and genetical mechanisms involved in carbohydrate metabolism and its regulation will improve the industrial use of LAB. LÄS MER

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

    Författare :Elisabet Roman; Marion Kusche-Gullberg; Hakon Leffler; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; UDP-glucose dehydrogenase; polysaccharide biosynthesis; glycosaminoglycan; A. thaliana; E. coli K5; Biokemi; Biochemistry; 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
