  2. 1. An albumin-binding domain as a scaffold for bispecific affinity proteins

    Author : Johan Nilvebrant; Sophia Hober; Andrew Bradbury; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; albumin-binding domain; bispecific; albumin; affinity protein; phage display; staphylococcal display; orthogonal affinity purification; TNF-alpha; ErbB2; ErbB3; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Abstract : Protein engineering and in vitro selection systems are powerful methods to generate binding proteins. In nature, antibodies are the primary affinity proteins and their usefulness has led to a widespread use both in basic and applied research. READ MORE

  4. 2. 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

  5. 3. 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

  6. 4. Evolutionary and functional studies of protein H: a surface molecule of Streptococcus pyogenes

    Author : Inga-Maria Frick; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracellular transportation; adhesion; aggregation; FNIII domain; albumin-binding; M-like protein; convergent evolution; protein G; Streptococcus pyogenes; IgG-binding; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Several bacterial species express surface proteins with affinity for the Fc part of human IgG. This thesis describes evolutionary and functional studies of protein H, an IgGFc-binding surface protein of the human pathogen Streptococcus pyogenes. READ MORE

  7. 5. Evasion and Attack: Structural Studies of a Bacterial Albumin-binding Protein and of a Cephalosporin Biosynthetic Enzyme

    Author : Sara Lejon; Janos Hajdu; Karin Valegård; Martin Noble; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; human serum albumin; GA module; albumin-binding; Finegoldia magna; deacetylcephalosporin C acetyltransferase; cephalosporin C; antibiotic; beta-lactam; biosynthesis; Acremonium chrysogenum; X-ray crystallography; Structural biology; Strukturbiologi;

    Abstract : This thesis describes the crystal structures of two proteins in the context of combatting bacterial infections. The GA module is a bacterial albumin-binding domain from a surface protein expressed by pathogenic strains of the human commensal bacterium Finegoldia magna. READ MORE
