  1. 11. On the crystallization of membrane proteins in lipidic sponge and cubic phases

    Författare :Pia Jeanette Hindrichsen; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; monoolein MO ; selachyl alcohol; cubic phase; sponge phase; small angle X-ray scattering; protein crystallization; phytantriol PT ;

    Sammanfattning : Membrane proteins are involved in many important biological processes and in order to understand their mechanism, their three-dimensional structures need to be elucidated to high resolution by for example X-ray crystallography. However, there is only limited structural knowledge for membrane proteins which is partly explained by the difficulties in obtaining well-diffracting crystals. LÄS MER

  3. 12. Phytoglobins: Elucidation of Structural, Functional and Practical Features of Non-Symbiotic Plant Hemoglobins

    Författare :Simon Christensen; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hemoglobin; Fytoglobin; Hexakoordination; Karaktärisering; Protein design; Rekombinant protein production; Kromatografi; kristallografi; Dimerisering; Protein Dynamik;

    Sammanfattning : Phytoglobins (Pgb) (plant hemoglobins) are heme-containing proteins and less well known in comparison to the mammalian counterparts hemoglobin (Hb) andmyoglobin (Mb). They share the same secondary structure as other globin-related proteins, six to eight α-helices comprising the myoglobin-fold (Mb-fold) with one prosthetic heme moiety per subunit. LÄS MER

  4. 13. Structural Insights at Sub-Ångstrom, Medium and Low Resolution: Crystallization of Trypsin, Bacterioferritin, Photosynthetic Reaction Center, and Photosynthetic Core Complex

    Författare :Weixiao Yuan Wahlgren; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein crystallization; cubic phase; sponge phase; bicelle; trypsin; bacterioferritin; reaction center; core complex; photosynthesis;

    Sammanfattning : The catalytic action of serine proteases depends on the interplay of a nucleophile, a general base and a general acid. The catalytic triad is composed of serine, histidine and aspartate residues. The serine acts as a nucleophile while the histidine plays a dual role as the general base or acid at different steps of the reaction. LÄS MER

  5. 14. Apolipoprotein M – Studies of Structure and Function

    Författare :Josefin Ahnström; Malmö Klinisk kemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal peptidase; signal peptide; crystallization; Apolipoprotein; lipocalin; HDL; coronary heart disease;

    Sammanfattning : Apolipoprotein M (apoM), a 25 kDa plasma protein, is found in all major lipoprotein classes, although the majority is found in high density lipoproteins (HDL). ApoM has been suggested to be involved in the formation of and adding to the antiatherogenic functions of HDL, but its function is still not completely known. LÄS MER

  7. 15. Utilization of Wild Fruit in Mozambique – Drying of Vangueria infausta (African medlar)

    Författare :Eulália Chiau; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vangueria infausta; drying; maltodextrin; sucrose; softener; toughness; solar-assisted pervaporation; aroma; crystallization; water activity;

    Sammanfattning : Vangueria infausta (African medlar) is a wild fruit found in southern and central Mozambique. The ripe fruit has a leathery skin enclosing three to five seeds embedded in a soft pulp that tastes like apple. It plays an important role in the diet of the rural population and has the potential for commercial use. LÄS MER
