  2. 16. Metal Affinity Peptides in Biotechnological Applications As tools in protein purification, protein stabilisation, metal quantification and metal tolerance of bacteria and plants

    Author : Malin Mejàre; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cadmium; metal quantification; fusion tag; metal affinity tag; phage display; peptide library; metal tolerance; metal resistance; metal accumulation; bioremediation; transgenic plant; tobacco; potato; protein purification; immobilised metal affinity chromatography; metal affinity precipitation; metal detection; protein stabilisation; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry; metal ion;

    Abstract : Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. READ MORE

  4. 17. Removal of metals from contaminated waters : Evaluating the use of synthetic adsorbents and green algae biomass

    Author : Roxana Quiroga Flores; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metals; toxicity; Adsorption; uptake; arsenic; cadmium; lead; methylmercury;

    Abstract : Metal contamination of water bodies has attracted global attention owing to its environmental toxicity, abundance and persistence. Metals such as arsenic, cadmium and mercury are of greater concern since they are toxic even at low concentrations. READ MORE

  5. 18. Structural aspecs on compounds in the CsI-(Cd/Hg)I2 system

    Author : Rune Sjövall; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tetrahedral distorsion; thermal decomposition; Biltz concept; structural relationships; hydrate; iodine; mercury; caesium; cadmium; coordination number modelling; Inorganic chemistry; Oorganisk kemi;

    Abstract : Structural investigations of compounds in the CsI-(Cd/Hg)I2 system have been performed by means of X-ray diffraction, thermogravimetric and calorimetric techniques. Crystals of the compounds studied were synthesized from aqueous solutions of CsI and CdI2/HgI2 by the slow evaporation of water. READ MORE

  6. 19. Effects of Endocrine Disrupting Chemicals on Human Endometrial Endothelial Cells In Vitro

    Author : Malin Helmestam; Matts Olovsson; Anneli Stavreus-Evers; Yvonne Lundberg Giwercman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endocrine disrupting chemicals; hormones; human endometrial endothelial cells; endometrium; estrogen; progesterone; cadmium; tamoxifen; mifepristone; bisphenol A; angiogenesis; Medicinsk vetenskap; Medical Science;

    Abstract : Evidence from an abundant number of studies suggests that human female reproductive functions have become impaired over the past half century and that there might be a relationship between endocrine disrupting chemicals (EDCs) and reduced fertility. It is, however, not known by what mechanisms EDCs affect different reproductive functions such as endometrial receptivity, embryo implantation and placentation. READ MORE

  7. 20. 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
