  2. 1. Single molecule dynamics

    Author : Lars Edman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Properties found in an ensemble of molecules may not be understood if it is not possible to study each molecule one by one. This thesis is concerned with the study of the dynamic properties of individual complex biological molecules as observed by confocal single-molecule fluorescence spectroscopy. READ MORE

  4. 2. Structural and dynamical basis of NusA´s role in transcription-coupled DNA repair

    Author : Damasus Okeke; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Resonance assignment; DNA repair; transcription-repair coupling factors; transcription-coupled repair; NusA; DinB; UvrD; autoinhibition; DNA substrate; dynamics.;

    Abstract : DNA repair processes involves a host of repair machineries that are able to recognize and repair the damaged DNA. Nucleotide excision repair (NER) pathway is one of these processes exploited by cells to remove bulky DNA lesions. READ MORE

  5. 3. Advanced computations and mass-spectrometric techniques to unravel the dynamics and interactions of proteins

    Author : Joana Costeira-Paulo; Erik Marklund; Lars Konermann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; mass spectrometry; dihydroorotate dehydrogenase; alpha-synuclein; protein structure; ion mobility; electrospray ionisation; collision cross section; lipids; gas-phase hydrogen deuterium exchange; collision induced unfolding; Biokemi; Biochemistry;

    Abstract : Proteins are an important class of biomolecules, involved in the metabolism, regulation, structure and transport in cells. Unfortunately, many diseases are caused by protein dysfunction. When proteins perform their normal function, they may interact with each other or change their conformation. READ MORE

  6. 4. Structure, dynamics and reactivity of carbohydrates : NMR spectroscopic studies

    Author : Jerk Rönnols; Göran Widmalm; Mikael Bols; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Conformation; NMR spectroscopy; Hydrogen bond; organisk kemi; Organic Chemistry;

    Abstract : The main focus of this thesis is on the ring conformations of carbohydrate molecules; how the conformational equilibria and the rates of the associated interconversions are affected by the molecular constitution and their surroundings.The conformational equilibria of a group of amine linked pseudodisaccharides, designed as potential glycosidase inhibitors, comprising α-D-altrosides are described in Chapter 3.

  7. 5. Ultrafast Dynamics in Ground and Excited States of Porphyrin Molecules

    Author : Peter Martinsson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intra- and intermolecular dynamics.; Zn-porphyrin; bacteriochlorophyll a; chlorophyll b; Femtosecond transient absorption spectroscopy; chlorophyll a; Physical chemistry; Fysikalisk kemi;

    Abstract : This thesis describes inter and intramolecular dynamics in porphyrin molecules. To create a basis for understanding the energy and electron transfer processes in photosynthesis, the ultrafast dynamics of monomeric chlorophyll a, chlorophyll b and bacteriochlorophyll a were studied with ultrashort laser pulses.
