  2. 1. 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

  4. 2. Structural and thermodynamical basis for molecular recognition between engineered binding proteins

    Author : Jakob Dogan; Per-Åke Nygren; John E. Ladbury; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein structure; induced fit; binding thermodynamics; NMR spectroscopy; protein engineering; protein-protein interactions; protein stability; calorimetry; Structural biochemistry; Strukturbiokemi;

    Abstract : The structural determination of interacting proteins, both as individual proteins and in their complex, complemented by thermodynamical studies are vital in order to gain in-depth insights of the phenomena leading to the highly selective protein-protein interactions characteristic of numerous life processes. This thesis describes an investigation of the structural and thermodynamical basis for molecular recognition in two different protein-protein complexes, formed between so-called affibody proteins and their respective targets.

  5. 3. The adenovirus DNA-binding protein : structure and function

    Author : Tommy Linné; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

  6. 4. Modelling the Protein-DNA Interface

    Author : Malin Lüking; Shina C. Lynn Kamerlin; Ehmke Pohl; Uppsala universitet; []
    Keywords : Protein-DNA interactions; Molecular Dynamics; Coarse-grained simulations; gene regulation; Biokemi; Biochemistry;

    Abstract : Protein-DNA interactions are crucial to life. Several millions of DNA base pair steps are organ- ised, read and protected by proteins in every cell. Protein-DNA interactions must be specific, controllable and reasonably fast. Understanding how these features coexist is one of the great challenges for biochemists and molecular biologists.

  7. 5. Protein Interactions: Electrostatics and Ligand Binding

    Author : Ingemar André; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; Molekylär biofysik; secondary structure formation; protein GB1; pKa values; pH stability; NMR; electrostatic interactions; M proteins; calbindin D9k; calcium binding; cooperativity; calmodulin; calbindin D28k;

    Abstract : This thesis deals with Ca2+ binding to proteins, electrostatic interactions in and between proteins as well as inter- and intramolecular interactions. A computer program was developed to determine Ca2+ binding constants from experimental titration data of proteins. READ MORE
