  1. 1. Perplexing Protein Puzzles

    Författare :Stina Lindman; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; calbindin D9k; split-GFP; protein G B1; pKa-values; protein reconstitution; Electrostatic interactions; protein stability; protein denaturation; heteronuclear NMR; pH titrations;

    Sammanfattning : Protein structure and stability are inherent in the amino acid sequence and governed by non-covalent interactions. The cooperation between forces is, however, perplexing and not well understood. In order to elucidate and predict protein folding and stability, detailed studies of non-covalent interactions are required. LÄS MER

  3. 2. Proteome wide protein production

    Författare :Hanna Tegel; Sophia Hober; Diethard Mattanovich; KTH; []
    Nyckelord :protein production; Escherichia coli; transcription; promoter; translation; rare codon; high-throughput; screening;

    Sammanfattning : Over a decade after the completion of the human genome, researchers around the world are still wondering what information is hidden in the genome. Although the sequences of all human genes are known, it is still almost impossible to determine much more than the primary protein structure from the coding sequence of a gene. LÄS MER

  4. 3. High-throughput protein analysis using mass spectrometry-based methods

    Författare :Tove Boström; Sophia Hober; Thomas Laurell; Ole N. Jensen; KTH; []
    Nyckelord :Proteomics; mass spectrometry; affinity proteomics; immunoenrichment; immunoprecipitation; IMAC; screening; protein production; protein purification; ISET; quantification; SILAC; stable isotope standard; antibody validation; Bioteknologi; Biotechnology;

    Sammanfattning : In the field of proteomics, proteins are analyzed and quantified in high numbers. Protein analysis is of great importance and can for example generate information regarding protein function and involvement in disease. Different strategies for protein analysis and quan- tification have emerged, suitable for different applications. LÄS MER

  5. 4. Unravelling protein stability and aggregation

    Författare :Tanja Weiffert; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein stability; protein aggregation; amyloid beta peptide; protein stabilization; split GFP; monellin; secretagogin; ; aggregation kinetics; toxicity; aggregation mechanism; coaggregation;

    Sammanfattning : Proteins are complex macromolecules that are fundamental to all living species. The stability of proteins are governed by non-covalent forces within the protein and between the protein and its surrounding environment. LÄS MER

  7. 5. Protein-protein interactions in model systems : design, control of catalytic activity and biosensor applications

    Författare :Johan Rydberg; Lars Baltzer; Joel Schneider; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Protein interactions; design; catalysis; biosensors; hybride materials; nanoparticles; Kemi; Chemistry; Kemi;

    Sammanfattning : This thesis describes the design of polypeptides, unordered in the monomeric state but capable of folding into helix-loop-helix motifs and dimerise to form four-helix bundles. The goal of the design was to encode them with the capacity to form dimers highly selectively and the ability to carry out molecular functions in the folded state but not in the unordered state, and thus to establish a molecular link between recognition and function.
