  1. 1. Unveiling Mechanistic Details of Macromolecular Interactions: Structural Design and Molecular Modelling of DNA-Protein Systems in Their Active State

    Author : Anna Reymer; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular modelling; intercalation; homologous recombination; DNA; ruthenium II polypyridyl compounds; human Rad51;

    Abstract : Molecular structure is fundamental for understanding mechanisms of molecular interactions. This applies not least to understanding biological function: every biological cell, whether bacterial or human, is an immensely complex system of thousands of molecules that exist in constant motion and interaction with each other.

    Abstract : Accurate predictions of protein structure are important for understanding many processes in cells. The interactions that govern protein folding and structure are complex, and still far from completely understood. However, progress is being made in many areas. Here, efforts to improve the overall quality of protein structure models are described. READ MORE

  3. 3. Structural dynamics of ribulose-1,5-bisphosphate carboxylase/oxygenase

    University dissertation from ; Department of Molecular Biology, Swedish University of Agricultural Sciences

    Author : Michiel Van Lun; Sveriges lantbruksuniversitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) assimilates carbon dioxide (CO2) from air into biomass. Due to its slow turnover, the reaction is a rate-limiting step in photosynthetic carbon fixation. READ MORE

  4. 4. Modeling of voltage-gated ion channels

    University dissertation from Stockholm : Department of Biochemistry and Biophysics. Stockholm University

    Author : Pär Bjelkmar; Erik Lindahl; Toby W. Allen; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular modeling; Molecular dynamics; Voltage-gating; Ion channels; Protein structure prediction; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

    Abstract : The recent determination of several crystal structures of voltage-gated ion channels has catalyzed computational efforts of studying these remarkable molecular machines that are able to conduct ions across biological membranes at extremely high rates without compromising the ion selectivity.Starting from the open crystal structures, we have studied the gating mechanism of these channels by molecular modeling techniques.

  5. 5. Topology Prediction of Membrane Proteins: Why, How and When?

    University dissertation from Stockholm : Institutionen för biokemi och biofysik

    Author : Karin Melén; Gunnar von Heijne; Hugh Salter; Janet Thornton; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; membrane protein; topology prediction; bioinformatics; NATURAL SCIENCES Chemistry Theoretical chemistry; NATURVETENSKAP Kemi Teoretisk kemi; biokemi; Biochemistry;

    Abstract : Membrane proteins are of broad interest since they constitute a large fraction of the proteome in all organisms, up to 20-30%. They play a crucial role in many cellular processes mediating information flow and molecular transport across otherwise nearly impermeable membranes. READ MORE
