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

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

    Abstract : 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. READ MORE

  4. 2. Microsomal glutathione transferase : catalysis, in vitro mutagenesis and heterologous expression

    Author : Rolf Weinander; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Microsomal glutathione transferase is a membrane-bound member of the glutathione transferases, a family of multifunctional enzymes involved in the cellular detoxification of xenobiotics and reactive endogenous compounds formed during oxidative stress. Rat liver microsomal glutathione transferase is a trimeric protein with a molecular mass of 17. READ MORE

  5. 3. Cystatin C functions in vitro and in vivo. Studies on target enzyme inhibition by cystatin C variants and cystatin C deficient mice

    Author : Katarina Håkansson; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloidosis; E.coli expression; Cysteine proteases; protease inhibitors; Clinical chemistry; Klinisk kemi;

    Abstract : Cystatin C variants with Arg8, Leu9 and/or Val10 replaced by Gly residues were produced by site-directed mutagenesis and E. coli expression. READ MORE

  6. 4. Cellular Uptake of Cystatin C. Subcellular localisation and intracellular effects of a secreted cysteine protease inhibitor

    Author : Hanna Wallin; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cathepsin; cell line; co-localisation; cystatin C; internalisation; legumain;

    Abstract : Cystatin C is a cysteine protease inhibitor, aimed for secretion, as it is produced with a signal peptide. Its target enzymes are thought to be the lysosomal cysteine cathepsins and legumain. READ MORE

  7. 5. Mutational analysis of melanocortin receptors 1 and 5

    Author : Per-Anders Frändberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Melanocortin receptor; melanocortin peptide; MSH; NDP-MSH; mutagenesis human phenotype; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics;

    Abstract : The melanocortin receptor family includes five subtypes, named MC1R to MC5R. Melanocortin receptors are predominantly coupled to second messenger pathway of cyclic AMP through coupling to G-protein. This study is focused on structure-function relationship of MC1R and MC5R. READ MORE
