  1. 1. Dynamics of Enzymes at Interfaces Lipase adsorption and mobility on solid surfaces

    Detta är en avhandling från Stockholm : KTH

    Författare :Andreas Sonesson; KTH.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biophysics; surface chemistry; diffusion; enzymes; lipases; adsorption; mobility; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : This thesis aimed to give more insight in the dynamics of enzymes at interfaces. The adsorption and mobility of adsorbed proteins can e.g. give a better understanding of structure-function properties of interfacially active enzymes. LÄS MER

  2. 2. Modelling of molybdopterin-dependent enzymes

    Detta är en avhandling från Anders Thapper, Inorganic Chemistry 1, Chemical Center, Lund University

    Författare :Anders Thapper; Lund University.; Lunds universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; enzymes; transition state; intermediate; mechanism; molybdopterin; density functional theory; model systems; oxygen atom transfer; molybdenum; tungsten; Oorganisk kemi; Chemistry; Kemi;

    Sammanfattning : The thesis deals with models for molybdopterin-dependent enzymes. Several model systems containing molybdenum or tungsten have been prepared and characterised, and their reactivity with oxygen atom acceptors and donors have been investigated. LÄS MER

  3. 3. Spectroelectrochemistry of Redox Enzymes

    Detta är en avhandling från Department of Analytical Chemistry, Lund University

    Författare :Andreas Christenson; Lund University.; Lunds universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elektrokemi; Electrochemistry; complex II; bilirubin oxidase; laccase; enzyme mechanism; redox potential; electron transfer; spectroelectrochemistry; redox enzymes; Spectroelectrochemical cell;

    Sammanfattning : A low volume and long optical path spectroelectrochemical cell was constructed and tested in a number of applications such as detection of direct electron transfer (DET) between redox enzymes and gold electrodes, determination of the formal potentials of redox centres in proteins and enzymes, as well as mechanistic studies of heterogeneous and intermolecular electron transfer of copper oxidases and succinate:quinine oxidoreductase (Complex II). The existence of DET between enzymes and electrodes was demonstrated for theophylline oxidase, cytochrome P450 cam, laccase, bilirubin oxidase, sulphite oxidase and Complex II. LÄS MER

    Sammanfattning : Cellulosabaserade material är världens rikligast förekommande förnyelsebara råvara. Växters cellväggar är naturliga kompositmaterial där den kristallina cellulosan är inbäddad i en väv av hemicellulosa, strukturproteiner och lignin. LÄS MER

  5. 5. Studies of Retroviral Reverse Transcriptase and Flaviviral Protease Enzymes as Antiviral Drug Targets Applications in Antiviral Drug Discovery & Therapy

    Detta är en avhandling från Acta Universitatis Upsaliensis : Uppsala universitet

    Författare :Muhammad Junaid; Uppsala universitet.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virus; enzymes; HIV AIDS; retroviral reverse transcriptase; flaviviral protease; NRTIs; proteochemometrics; drug resistance; DEN; JEV; NS2B H -NS3pro; antiviral; drug targets; drug discovery; drug therapy.; Farmakologi; Pharmacology;

    Sammanfattning : Viruses are a major threat to humans due to their unique adaptability, evolvability and  capability to control their hosts as parasites and genetic elements. HIV/AIDS is the third largest cause of death by infectious diseases in the world, and drug resistance due to the viral mutations is still the leading cause of treatment failure. LÄS MER
