  2. 1. Transaminase Biocatalysis: Applications and Fundamental Studies

    Author : Federica Ruggieri; Per Berglund; Mariarita Bertoldi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocatalysis; enzymatic cascade; transaminase; amine; racemization; PLP; enzyme engineering; Chromobacterium violaceum; protein stability; enzyme stability; molecular dynamics; structural biology; enzyme technology; chiral amines; kinetic resolution; Bioteknologi; Biotechnology;

    Abstract : Biocatalysis is the branch of science at the intersection between chemistry and biology and specifcally dedicated to the application of natural evolvable catalysts, i.e. enzymes, in human-designed chemical processes. Among the array of promising biocatalysts, transaminases (EC 2. READ MORE

  4. 2. Thermal tolerance in teleost fish –importance of cardiac oxygen supply, ATP production and autonomic control

    Author : Andreas Ekström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acclimation; coronary; CTmax; enzyme; global warming; heart; mitochondria;

    Abstract : Temperature tolerance is a key determinant of the resilience and adaptability of fish facing a warmer and more thermally variable future with climate change. Yet, the underlying physiological mechanisms determining the critical thermal maximum (CTmax) are poorly understood. READ MORE

  5. 3. Malassezia-related diseases

    Author : Aditya Gupta; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Malassezia; dermatoses; yeasts; pityriasis versicolor; atopic dermatitis; seborrheic dermatitis; psoriasis;

    Abstract : The purpose of this thesis is to investigate whether the new taxonomy of Malassezia may have important clinical implications. In particular, the studies look at pityriasis versicolor and other dermatological disorders associated with Malassezia yeasts to see whether there is a clear association between the yeast species and body site colonized and/or disease state.

  6. 4. Transition metal- and lipase-catalyzed reactions : Dynamic resolutions, hydrogen transfer and enzyme engineering

    Author : Patrik Krumlinde; Jan-Erling Bäckvall; Johannes G. de Vries; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dynamic kinetic resolution; dynamic kinetic asymmetric transformation; hydrogen transfer; directed evolution; enzyme engineering; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis mainly focuses on chemoenzymatic processes and can be divided into three parts: The first part of the thesis, chapters 2-4, is devoted to the development of combined ruthenium- and enzyme-catalyzed dynamic processes. In these processes the metal catalyst racemizes (epimerizes) the alcohol substrate via hydrogen transfer and the enzyme transforms the substrate into enantiomerically enriched product. READ MORE

  7. 5. Kallikrein-related peptidases in human epidermis : studies on activity, regulation, and function

    Author : Kristina Stefansson; Torbjörn Egelrud; Maria Brattsand; Mona Ståhle; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; desquamation; epidermis; stratum corneum; kallikrein-related peptidase; KLK; serine protease inhibitors; Dermatology and venerology; Dermatologi och venerologi;

    Abstract : Introduction. The outermost layer of the epidermis, the stratum corneum (SC), plays a fundamental role in our defense against microorganisms, chemicals, and dehydration. The SC is composed of tightly packed keratinized skin cells, corneocytes. For a functioning skin it is essential that corneocytes are constantly shed (desquamated). READ MORE
