1. 16. Interactions between streptococcal M proteins and human plasma proteins

   Författare :Charlotta Sandin; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; innate immunity; Streptococcus pyogenes; phagocytosis resistance;

   Sammanfattning : Streptococcus pyogenes is a common human pathogen, which causes a variety of diseases. A major virulence factor of S. pyogenes is the surface-associated M protein, which mediates resistance to phagocytosis. Several studies indicate that M proteins inhibit complement deposition and thereby phagocytosis. LÄS MER

3. 17. 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

4. 18. Interaction of Triglyceride-rich Lipoproteins with Platelets and Vitamin K-dependent Coagulation Factors

   Författare :Ning Xu; Avdelningen för klinisk kemi och farmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Triglycerides.; Prothrombin; Protein S; Protein C; Platelets; Phospholipids; Metabolism; Lipoproteins; Lipids; Endocytosis; Electron microscopy; Cytochemistry; Coronary heart disease; Blood coagulation factors; Arachidonic acid; Atherosclerosis; Clinical chemistry; Klinisk kemi; Haematology; extracellular fluids; Hematologi; extracellulära vätskor;

   Sammanfattning : 1. During incubation of platelets with 3H-arachidonic acid (20:4, n-6) and 14C-cholesterol doubly labelled and colloidal gold labelled chylomicrons (CMs) and chylomicron remnants (CMRs) CMs were taken up more efficiently than CMRs. Addition of unlabelled CMs, VLDLs, LDLs and HDLs decreased the uptake of labelled CMs. LÄS MER

5. 19. Protein Interactions Involving the Laminin G-type Domains of Vitamin K-dependent Protein S

   Författare :Petra Evenäs; Malmö Klinisk kemi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; tyrosine phosphorylation.; Sky receptor; SHBG-like region; protein S; G domain; Gas6; Activated protein C; C4b-binding protein; Proteins; enzymology; Proteiner; enzymologi;

   Sammanfattning : The studies described in this thesis focus on the involvement of the two laminin G-type domains of vitamin K-dependent protein S in various biological contexts. The G-type domains are located in the C-terminal sex-hormone-binding globulin (SHBG)-like region. LÄS MER

7. 20. The EGF-like Modules of Anticoagulant Protein S. Studies of Ca2+ binding and module interactions

   Författare :Yvonne Stenberg; Malmö Klinisk kemi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enzymology; Proteins; Klinisk kemi; Clinical chemistry; calcium binding; Protein S; EGF-like module; Proteiner; enzymologi;

   Sammanfattning : Protein S functions as a cofactor to activated protein C (APC) in the degradation of factors Va and VIIIa. In plasma protein S circulates in two forms; 30-40 % circulates as free protein S molecules while the remaining 60-70 % exists in a 1:1 complex with C4b-binding protein (C4BP). Only the free form of protein S functions as a cofactor to APC. LÄS MER
