  1. 1. Plant type II NAD(P)H dehydrogenases : Structure, regulation and evolution of NDB proteins

    Författare :Mengshu Hao; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; Ca2 ; Electron transport; NDH-2; NDB; pH; NADH; NADPH; Plant mitochondria; Potato; Type II NAD P H dehydrogenase;

    Sammanfattning : In living organisms, respiration is a biological process degrading different carbon substrates, consuming O2, and releasing the carbon as CO2. Plants have several alternative enzymes that are involved in the respiratory processes, as compared to animals. LÄS MER

  3. 2. Respiratory NAD(P)H dehydrogenases of plants - Gene identity and expression in response to light and cold

    Författare :Staffan Svensson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; morfologi; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morphology; taxonomy; Systematic botany; Växtgenetik; Plant genetics; plant mitochondria; NADH dehydrogenases; light dependence; mRNA quantification; leaf respiration; cold treatment; kemotaxonomi.

    Sammanfattning : The respiratory chain of plants contains class 2 NAD(P)H dehydrogenases, not present in animals. The functional roles of these enzymes have been elusive for a long time. Two cDNAs, homologous to class 2 NADH dehydrogenase genes of yeast and E. coli, were isolated from potato leaves. LÄS MER

  4. 3. Medium chain dehydrogenases/reductases : alcohol dehydrogenases of novel types

    Författare :Annika Norin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Alcohol dehydrogenase; Nicotinoproteins; Structural interpretations; Functional properties; Molecular evolution.;

    Sammanfattning : The medium chain dehydrogenase/reductase (MDR) superfamily is separated into at least eight families, of which the dimeric alcohol dehydrogenase (ADH) is one. Including species variants, close to 1000 MDR forms have been characterized. LÄS MER

  5. 4. Mechanism of Metabolite transfer between Enzymes in Glycolysis and Connected Pathways

    Författare :Wilma Martinez Arias; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Channelling; Free-diffusion; Glycolytic pathway; Dehydrogenases; Enzyme kinetics; Biochemistry; Metabolite transfer mechanism.; Biokemi; Metabolism;

    Sammanfattning : The metabolite produced by one enzyme in a metabolic pathway can be transferred to the next enzyme in the pathway by free diffusion via solution or by channelling in an enzyme-enzyme complex without prior release of the metabolite to solution. While metabolite channelling is known to occur in systems where stable multienzyme complexes form, conflicting views have been expressed as to its existence in pathways involving "soluble" enzymes.

  7. 5. Functional studies of the TDH and GPD gene-products in the glycolytic flux and glycerol metabolism of Saccharomyces cerevisiae

    Författare :Hadi Valadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Growth rate; GPD; Sacchromyces cerevisiae; Glyceol; NADH; Anaerobiosis; TDH; Redox; Glycolysis;

    Sammanfattning : This thesis focuses on the physiology and control of the glycolysis and glycerol metabolism in the yeast Sacchromyces cerevisiae. The study is based on the relation ship between the first two reactions around the branch-point of the upper and lower part of glycolysis and the glycerol pathway. LÄS MER
