  2. 2. Enzymatic treatment of wastewater sludge. Sludge solubilisation, improvement of anaerobic digestion and extraction of extracellular polymeric substances

    Författare :Joanna Wawrzynczyk; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pollution control; Environmental technology; sludge treatment; wastewater activated sludge; Proteins; enzymology; Proteiner; enzymologi; cation-binding agents; mass reduction; lectins; extracellular polymeric substances; enzymes; enzymatic activity; anaerobic digestion; biogas; Miljöteknik; kontroll av utsläpp; Biotechnology; Bioteknik;

    Sammanfattning : The processing and disposal of sludge from wastewater treatment plants is an important topic of increasing environmental, ecological, technological, economic and social concern. The large amounts of sludge produced represent an urgent problem today, new treatment methods being very much needed. LÄS MER

  3. 3. Aldolases for Enzymatic Carboligation : Directed Evolution and Enzyme Structure-Function Relationship Studies

    Författare :Huan Ma; Mikael Widersten; Wolf-Dieter Fessner; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; aldolase; 2-deoxyribose-5-phosphate aldolase; fructose-6-phosphate aldolase; directed evolution; enzyme dynamics; Biokemi; Biochemistry;

    Sammanfattning : The research summarized in this thesis focuses on directed evolution and enzyme mechanism studies of two aldolases: 2-deoxyribose-5-phosphate aldolase (DERA) and fructose-6-phosphate aldolase (FSA).Aldolases are nature’s own catalysts for one of the most fundamental reactions in organic chemistry: the formation of new carbon-carbon bonds.

  4. 4. Enzymatic Regulation of Steroidogenesis and Nuclear Receptor Activation : Special Focus on Vitamin D and Sex Hormones

    Författare :Johan Lundqvist; Kjell Wikvall; Maria Norlin; Magnus Ingelman-Sundberg; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenal steroidogenesis; CYP7B1; vitamin D; calcitriol; enzymatic regulation; transcriptional regulation; CYP21A2; aromatase; sex hormone; estrogen; androgen; nuclear receptor; Pharmaceutical biochemistry; Farmaceutisk biokemi; Farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Sammanfattning : Enzyme-catalyzed reactions are important to regulate steroidogenesis and nuclear receptor activation. The present investigation examines the role of steroid metabolism catalyzed by CYP7B1 for regulation of hormone receptor activation and the effects of vitamin D on enzymatic regulation of steroidogenesis.

  5. 5. LL-37-derived cyclic antimicrobial drug leads : Design, synthesis, activity and different ways of creating them 

    Författare :Taj Muhammad; Ulf Göransson; Sunithi Gunasekera; Adam A. Strömstedt; Wang Guangshun; Uppsala universitet; []
    Nyckelord :antimicrobial peptide; host defense; antimicrobial; LL-37; KR-12; peptide cyclisation; peptide dimerisation; croos-linking; cyanobactin-macrocyclase; PatGmac; butelase 1; enzymatic cyclisation; immobilisation; Farmakognosi; Pharmacognosy;

    Sammanfattning : In an era where last-line antibiotics are failing, one of the powerful approaches to develop novel therapeutic agents is to turn back to nature in order to identify possible drug candidates. Among the potential candidates, antimicrobial peptides (AMPs) have garnered much attention as an antimicrobial. LÄS MER
