  2. 1. Computational Protein Evolution : Modeling the Selectivity and Promiscuity of Engineered Enzymes

    Author : Klaudia Szeler; Shina C. Lynn Kamerlin; Mikael Widersten; Maria Ramos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; enzymes; kinetics; catalysis; density functional theory; empirical valence bond; diesters; evolution; promiscuity; Biokemi; Biochemistry;

    Abstract : Enzymes are biological catalysts that significantly increase the rate of all biochemical reactions that take place within cells and are essential to maintain life. Many questions regarding their function remain unknown. READ MORE

  4. 2. Genome Evolution and Host Adaptation in Bartonella

    Author : Eva Caroline Berglund; Siv GE Andersson; Brendan Wren; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bartonella; genome evolution; genome diversity; phage; gene transfer agent; secretion system; microarray; Bioinformatics; Bioinformatik; Evolutionary Genetics; evolutionär genetik;

    Abstract : Bacteria of the genus Bartonella infect the red blood cells of a wide range of wild and domestic mammals and are transmitted between hosts by blood-sucking insects. Although most Bartonella infections are asymptomatic, the genus contains several human pathogens. READ MORE

  5. 3. Mobility and emigration in butterflies

    Author : Karin Enfjäll; Olof Leimar; Michel Baguette; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Keywords: conspecific density; dispersal; evolution; flight-behaviour; information; sexual conflict; social interactions; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

    Abstract : Because of its implications for the survival of many species, dispersal plays a key role in conservation biology. A good knowledge about the different factors that influence dispersal decisions is crucial for the understanding of inter-population movements. READ MORE

  6. 4. Exploring the Role of the PDZ Domain in a Supramodule

    Author : Louise Laursen; Per Jemth; Per Hammarström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PSD-95; PSG; PDZ3; supramodule; liquid liquid phase separation; allostery; folding; binding; evolution; post synaptic density; SynGap; CRIPT; AGRB1; Medical Biochemistry; Medicinsk biokemi; Medical Biochemistry; Medicinsk biokemi;

    Abstract : The postsynaptic density (PSD) is a large, dense and membraneless compartment of proteins associated below the postsynaptic membrane bilayer, and which constantly undergoes morphological alteration in response to synaptic activity. Formation of PSD is associated with liquid-liquid phase separation of scaffold proteins in complex with other PSD proteins. READ MORE

  7. 5. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

    Author : Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. READ MORE
