  2. 1. Synthesis and Studies of NADH Models: Stereoselective Reductions and Host-Guest Properties

    Author : Ulrik Gran; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; synthesis; NADH model; host-guest complex; stereoselective reductions; macrocyclic; reducing agent;

    Abstract : The aim of the project has been to synthesise macrocyclic NADH models and to study them as reducing agents and hosts. Three types of macrocyclic NADH models have been synthesised. They consist of the same subunits; a chiral unit, a nicotinamide unit and an aromatic spacer. READ MORE

  4. 2. Biochemical Control Aspects in Lignin Polymerization

    Author : Anders Holmgren; Gunnar Henriksson; Liming Zhang; Jussi Sipilä; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignin polymerization; DHP; Ascorbic Acid; NADH; template polymerization; melanin; Chemistry; Kemi;

    Abstract : Lignins are produced by all vascular plants and they represent one of the most abundant groups of biopolymers in nature. Lignin chemistry research, which has been of great importance for the progress of pulping technologies, has been plagued by the difficulties of its isolation and characterization. READ MORE

  5. 3. Gene fusion in protein engineering : design of novel peptides and bifunctional enzymes

    Author : Sarah Fredriksson; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cadmium; Bifunctional enzyme; Catalytic triad; Channeling; Coenzyme recycling; Galactose dehydrogenase; ß-Galactosidase; Gene fusion; Hexapeptide; Lactate dehydrogenase; Linker region; Multifunctional enzymes; Oligomeric protein; NADH; Phage; OmpA; Biochemistry; Biokemi; metabolism; Biotechnology; Bioteknik;

    Abstract : The gene fusion technique is widely used in protein engineering and in this thesis it constitutes the basis of both the construction of artificial bifunctional enzymes and the display of two novel peptides. Artificial bifunctional enzymes have been used as model systems in the studies of native multifunctional enzymes and proximity effects within these complexes. READ MORE

  6. 4. Glycolytic oscillations in individual yeast cells

    Author : Anna-Karin Gustavsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical manipulation; Microfluidics; Fluorescence microscopy; Single cell analysis; Saccharomyces cerevisiae; Glycolysis; Oscillations; NADH; Heterogeneity; Synchronization; Robustness; Universality;

    Abstract : Oscillations in the concentration of yeast glycolytic intermediates have been intensively studied since the 1950s, but these studies have so far been limited to observations of average oscillatory behavior in synchronized cultures. Hence, it has remained unknown whether the onset of oscillations is a collective property of the population which requires a high cell density, or if individual cells can oscillate also in isolation.

  7. 5. NADH:quinone oxidoreductase: the black box of the respiratory chain

    Author : Robert Roth; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NADH:quinone oxidoreductase; Complex I; electron transport; membrane protein; ubiquinone; respiratory chain; respiration; metabolism; Metabolism; Biokemi; Biochemistry;

    Abstract : Complex I or NADH:quinone oxidoreductase the largest, most complex and least understood of the five membrane-bound enzyme complexes constituting the mitochondrial respiratory chain. The enzyme is present in all types of organisms, from bacteria to mammals. READ MORE
