1. 11. C4b-binding protein: Identification of binding sites and a possible function of the interaction with protein S

   Författare :Joanna Webb; Malmö Klinisk kemi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical chemistry; apoptosis; binding sites; complement; C4b-binding protein; protein S; Klinisk kemi;

   Sammanfattning : The subject of this thesis is plasma protein C4b-binding protein (C4BP). C4BP is an important regulator of the classical pathway of the complement system, a cascade-like system comprised of over 35 proteins, which partakes in the defence against micro-organisms and is involved of clearance of immune-complexes and apoptotic cells.

3. 12. Advances in Ligand Binding Predictions using Molecular Dynamics Simulations

   Författare :Henrik Keränen; Johan Åqvist; Jordi Villà i Freixa; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; free-energy perturbation; molecular dynamics; ligand binding; free-energy perturbation; linear interaction energy; binding free-energy; homology modeling; virtual screening; alanine scanning; amino acid mutagenesis; hERG; GPCR; adenosine receptor; serotonin receptor; BRICHOS; cruzain;

   Sammanfattning : Biochemical processes all involve associations and dissociations of chemical entities. Understanding these is of substantial importance for many modern pharmaceutical applications. In this thesis, longstanding problems with regard to ligand binding are treated with computational methods, applied to proteins of key pharmaceutical importance. LÄS MER

4. 13. Protein Interactions: Electrostatics and Ligand Binding

   Författare :Ingemar André; Biofysikalisk kemi; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 14. Functional studies and engineering of family 1 carbohydrate-binding modules

   Författare :Janne Lehtiö; KTH; []
   Nyckelord :Cellulose-binding; carbohydrate-binding modules; phage display; bacterial surface display; combinatorial protein library; protein engineering; Trichoderma reesei; Staphylococcus carnosus;

   Sammanfattning : The family 1 cellulose-binding modules (CBM1) form a groupof small, stable carbohydrate-binding proteins. These modulesare essential for fungal cellulosedegradation. This thesisdescribes both functional studies of the CBM1s as well asprotein engineering of the modules for several objectives. LÄS MER

7. 15. Infrared spectroscopy : Method development and ligand binding studies

   Författare :Saroj Kumar; Andreas Barth; Janos Mink; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Infrared; Ligand binding; method development; Biophysical chemistry; Biofysikalisk kemi; biofysik; Biophysics;

   Sammanfattning : Infrared spectroscopy detects molecular vibrations and assesses the properties of molecules and their environment. It is a powerful technique to detect ligand induced changes in biomolecules as it has distinct signals and provides different levels of structural information. LÄS MER
