  1. 1. Folding and Structure of Azurin - The Influence of a Metal

    Författare :Johan Leckner; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; azurin; metal cofactor; disulfide bond; protein folding; solution structure; protein stability; paramagnetic NMR;

    Sammanfattning : The structural role of the metal in the protein azurin from Pseudomonas aeruginosa has been a long standing question. Azurin belongs to the cupredoxin family and is a 128 residue beta-barrel protein of greek-key topology. LÄS MER

  3. 2. Protein Engineering on Azurin. Expression Mutagenesis and Characterisation of Copper Site Mutants

    Författare :B Göran Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EPR spectroscopy; cassette mutagenesis; optical spectroscopy; amino acid exchange; Escherichia coli; electron transfer; reduction; azurin;

    Sammanfattning : Azurin belongs to a family of small blue copper proteins or cupredoxins which participate in electron transfer processes in plants and bacteria. The type 1 copper site in these proteins is characterised by an intense blue colour, a narrow hyperfine coupling in the EPR signal and, generally, a high reduction potential. LÄS MER

  5. 4. Theoretical studies of blue copper proteins

    Författare :Mats H M Olsson; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum chemistry; metal-thiolate bonds; axial ligation; electron transfer proteins; reduction potential; reorganisation energy; Cu II ; Cu I ; strain; Induced-rack theory; Entatic state theory; cytochrome c oxidase; CuA; nitrite reductase; azurin; Blue copper proteins; plastocyanin; B3LYP; CASPT2; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära;

    Sammanfattning : In this thesis, a critical investigation is presented about the role of mechanical strain for the electron-transfer properties of the blue copper proteins. It has been found that the structure of a realistic model complex of the oxidised blue-copper active site, optimised in vacuum with the B3LYP method, has the same trigonal cupric geometry as in the protein.
