  2. 6. Engineering carbonic anhydrase for highly selective ester hydrolysis

    Author : Gunnar Höst; Bengt-Harald Jonsson; Lars-Göran Mårtensson; Per Berglund; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbonic anhydrase; specificity; hydrolysis; rational design; protein engineering; plasmodium falciparum; Bioengineering; Bioteknik;

    Abstract : I denna avhandling presenteras arbete utfört med enzymet humant karboanhydras II (HCAII). Enzymer är en typ av proteiner som accelererar (katalyserar) kemiska reaktioner, vilket är nödvändigt för allt levande. Den naturliga funktionen för HCAII är att katalysera omvandlingen av gasen koldioxid till vätekarbonat, som är löslig i vätska. READ MORE

  4. 7. Metaproteogenomics-guided enzyme discovery : Targeted identification of novel proteases in microbial communities

    Author : Mikaela Johansson; Martin Karlsson; Bengt-Harald Jonsson; Florian-Alexander Herbst; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Industrial biotechnology is a large and growing industry as it is part of establishing a “greener” and more sustainable bioeconomy-based society. Using enzymes as biocatalysts is a viable alternative to chemicals and energy intense industrial processes and is en route to a more sustainable industry. READ MORE

  5. 8. Reaction Mechanism and Allosteric Regulation of Class Ia Ribonucleotide Reductase from Escherichia coli

    Author : Alex Kasrayan; Britt-Marie Sjöberg; Bengt-Harald Jonsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi;

    Abstract : Ribonculeotide reductase (RNR) plays a key role in catalysing a reaction that provides all living organisms with building blocks for DNA. The RNR enzyme catalyses the conversion of ribonucleotides to their corresponding deoxyribonucleotides, by using free radical chemistry. READ MORE

  6. 9. Zinc in folding and misfolding of SOD1 : Implications for ALS

    Author : Lina Leinartaité; Mikael Oliveberg; Bengt-Harald Jonsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein stability; protein misfolding; local unfolding; metal binding; energy landscape; protein disease; amyotrophic lateral sclerosis; Biochemistry; biokemi;

    Abstract : Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease causing degeneration of upper and lower motor neurons. Most ALS cases are sporadic; only 6% are associated with mutations in Cu, Zn superoxide dismutase (SOD1). READ MORE

  7. 10. Biophysical studies of protein folding upon interaction with molecular chaperones

    Author : Satish Babu Moparthi; Uno Carlsson; Per Hammarström; Bengt-Harald Jonsson; Pernilla Wittung‐Stafshede; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Proteins are biological macromolecules that serve all functions in cells. Every protein consists of a sequence of amino acids that is folded into a three‐dimensional structure to maintain the unique information it contains and to allow the protein to perform its specific actions.
