2. 1. NMR Studies of Bacterial Albumin-Binding Modules

   Author : Maria U Johansson; Biofysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Biotechnology; Bioteknik; Proteins; enzymology; Proteiner; enzymologi; Physical chemistry; three-helix bundle; protein structure; protein PAB; protein-protein interactions; protein G; protein dynamics; NMR; module shuffling; GA module; evolution; albumin-binding; bacterial surface proteins;

   Abstract : Peptostreptococcus magnus and group C/G streptococci are Gram-positive cocci that are part of the normal flora and reside in more or less the same locations in the host. Protein G of group C/G streptococci was originally described as binding IgGFc of several species and later shown to also bind human serum albumin and albumins from various animal species. READ MORE

4. 2. Molecular principles of protein stability and protein-protein interactions

   Author : Christofer Lendel; Per-Åke Nygren; Christopher M. Dobson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affibody; binding thermodynamics; induced fit; molten globule; NMR spectroscopy; protein engineering; protein-protein interactions; protein stability; protein structure.; Structural biochemistry; Strukturbiokemi;

   Abstract : Proteins with highly specific binding properties constitute the basis for many important applications in biotechnology and medicine. Immunoglobulins have so far been the obvious choice but recent advances in protein engineering have provided several novel constructs that indeed challenge antibodies. READ MORE

5. 3. Perplexing Protein Puzzles

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

   Abstract : 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. READ MORE

6. 4. Development and applications of NMR relaxation methods to study protein and ligand dynamics

   Author : Sven Wernersson; Biofysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear magnetic resonance; NMR; NMR relaxation; Method development; Protein dynamics; BRD4; Galectin 3; Kärnmagnetisk resonansspektroskopi; proteindynamik; Metodutveckling; NMR; BRD4; Galektin 3;

   Abstract : This thesis involves the study of proteins. These molecules exist in many variants, and perform most of our bodily functions. This includes signaling (for example the presence of capsaicin, which makes food spicy), molecular transport (including oxygen), catalysis (including food digestion) and part of our body structure (such as muscles).

7. 5. Structure determination and thermodynamic stabilization of an engineered protein-protein complex

   Author : Elisabet Wahlberg; Per-Åke Nygren; Bengt-Harald Jonsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affibody; protein structure; coupled folding; NMR spectroscopy; protein stability; protein-protein interactions; binding thermodynamics; isothermal titration calorimetry; protein engineering; Structural biochemistry; Strukturbiokemi;

   Abstract : The interaction between two 6 kDa proteins has been investigated. The studied complex of micromolar affinity (Kd) consists of the Z domain derived from staphylococcal protein A and the related protein ZSPA-1, belonging to a group of binding proteins denoted affibody molecules generated via combinatorial engineering of the Z domain.
