  2. 11. Using de novo design proteins to explore tyrosine radicals and cation-π interactions

    Author : Bruce W. Berry; Cecilia Tommos; Anders Hofer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tyrosine; radicals; cation-pi interactions; de novo designed proteins; biochemistry; biophysics; Biochemistry; biokemi;

    Abstract : Redox cofactors and amino-acid free radicals play important roles in biology. Although many of the same cofactors and amino acids that form these radicals are found across a broad range of biological systems, identical cofactors can have different reduction potentials. The local environment plays a role in defining these redox potentials.

  4. 12. Influences of in vivo and in vitro loading on the proteoglycan synthesis of articular cartilage chondrocytes

    Author : Mikko Lammi; Markku Tammi; Jukka Finne; Tim Hardingham; Finland Kuopio University of Kuopio Department of Anatomy; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Articular cartilage; proteoglycans; loading; stress; hydrostatic pressure; biokemi; Biochemistry; cell research; cellforskning; molekylärbiologi; Molecular Biology; ortopedi; Orthopaedics;

    Abstract : In this study, the biosynthesis of proteoglycans (PGs) was examined in articular cartilage of canine hip joint after long-distance running experiment and in bovine chondrocyte cultures during in vitro loading with hydrostatic pressure. In addition, new assays were developed for more sensitive quantitation of glycosaminoglycans (GAGs) and PGs. READ MORE

  5. 13. Application of membrane protein topology prediction

    Author : Aron Hennerdal; Arne Elofsson; Rita Casadio; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

    Abstract : Membrane proteins often have essential functions in the cell and many are important drug targets, yet only a small fraction of available protein structures are of membrane proteins. Experimental techniques for elucidating membrane protein structures have proven laborious and expensive, opening the field for comparatively inexpensive computational modeling. READ MORE

  6. 14. Structural and functional studies of protein complexes involved in energy metabolism

    Author : Jens Berndtsson; Martin Ott; Irene Diaz-Moreno; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mitochondria; metabolism; OXPHOS; yeast respiratory supercomplex; cytochrome c; coenzyme Q; pyruvate dehydrogenase complex; Biochemistry; biokemi;

    Abstract : Mitochondria are eukaryotic organelles with a multitude of functions including biosynthesis of molecules and cellular regulation. Most prominently though is their role in energy conversion which culminates with the production of ATP, the universal molecular unit of currency. READ MORE

  7. 15. Protein Folding Studies on the Ribosomal Protein S6: the Role of Entropy in Nucleation

    Author : Magnus Lindberg; Mikael Oliveberg; Jane Clarke; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; protein folding; circular permutation; topology; connectivity; entropy; protein stability; chevron plot; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : One of the most challenging tasks remaining in the field of biochemistry is the one of understanding how the information within the amino acid sequence of proteins translates into a unique structure. Solving this problem would lead to endless possibilities for application in the medical and biotechnology industry. READ MORE
