  1. 6. 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.

  2. 7. From protein sequence to structural instability and disease

    Author : Lixiao Wang; Uwe Sauer; Sven Hovmöller; Umeå universitet; []
    Keywords : protein domain; remote homologue; intrinsically disorder unstructured proteins; protein function; point mutation; protein family protein stability; HMMs; CRFs; SVMs;

    Abstract : A great challenge in bioinformatics is to accurately predict protein structure and function from its amino acid sequence, including annotation of protein domains, identification of protein disordered regions and detecting protein stability changes resulting from amino acid mutations. The combination of bioinformatics, genomics and proteomics becomes essential for the investigation of biological, cellular and molecular aspects of disease, and therefore can greatly contribute to the understanding of protein structures and facilitating drug discovery.

  3. 8. Protein engineering to explore and improve affinity ligands

    Author : Martin Linhult; KTH; []
    Keywords : binding; affinity; human serum albumin HSA ; albumin-binding domain ABD ; affinity chromatography; deamidation; protein A; stabilization; Z-domain; capacity; protein G; cleaning-in-place CIP ; protein engineering; C2 receptor;

    Abstract : In order to produce predictable and robust systems forprotein purification and detection, well characterized, small,folded domains descending from bacterial receptors have beenused. These bacterial receptors, staphylococcal protein A (SPA)and streptococcal protein G (SPG), possess high affinity to IgGand / or HSA. READ MORE

  4. 9. Protein structure prediction : Zinc-binding sites, one-dimensional structure and remote homology

    Author : Nanjiang Shu; Sven Hovmöller; Bruce Donald; Geoff Barton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein structure prediction; zinc-binding; profile; homology detection; shape string; Bioinformatics; Bioinformatik; Molecular biology; Molekylärbiologi; Biochemistry; Biokemi; Structural Chemistry; strukturkemi;

    Abstract : Predicting the three-dimensional (3D) structure of proteins is a central problem in biology. These computationally predicted 3D protein structures have been successfully applied in many fields of biomedicine, e.g. family assignments and drug discovery. READ MORE

  5. 10. Physical Modeling of Protein Folding

    Author : Stefan Wallin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; relativity; quantum mechanics; classical mechanics; three-helix bundle; similarity measure; Mathematical and general theoretical physics; protein dynamics; protein folding; two-state; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2003:Wallin;

    Abstract : Sequence-based models for protein folding are developed and tested on peptides with both alpha- and beta-structure, and on small three-helix-bundle proteins. The interaction potentials of the models are minimalistic and based mainly on hydrogen bonding and effective hydrophobicity forces. READ MORE
