  1. 6. Structure-Function Relationships of Pi Class Glutathione Transferase Studied by Protein Engineering

    Författare :Usama M. Hegazy; Bengt Mannervik; Mikael Widersten; T. J. Mantle; Uppsala universitet; []
    Nyckelord :Biochemistry; Glutathione transferase; targeted chemical modification; lock-and-key motif; cooperativity; stucture-function relationship; protein engineering; unnatural amino acid; site-specific mutation; Biokemi;

    Sammanfattning : The glutathione transferases (GSTs) represent a superfamily of dimeric proteins involved in cellular detoxication by catalyzing the nucleophilic addition of the reduced glutathione (GSH) to the hydrophobic electrophiles. The present work focuses on the functional role of the conserved structures of GSTP1-1. LÄS MER

  2. 7. FtsH metalloproteases and their pseudo-proteases in the chloroplast envelope of Arabidopsis thaliana

    Sammanfattning : By cleaving peptide bonds, proteases either activate or degrade proteins and maintain protein quality control in response to various developmental stimuli and environmental factors. My work has focused on elucidating the role of the filamentation temperature sensitive protein H (FtsH) proteases. LÄS MER

  3. 8. Short-chain dehydrogenases/reductases : structure, function and motifs of hydroxysteroid dehydrogenases

    Författare :Charlotta Filling; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Short-chain dehydrogenases reductases; site-directed mutagenesis; steady-state kinetics; X-ray structure; enzyme function; steroid; motif; reaction mechanism; 3 beta 17 beta-hydroxysteroid dehydrogenase; 17 beta-hydroxysteroid dehydrogenase; short chain hydroxyacyl coenzyme A dehydrogenase;

    Sammanfattning : Short-chain dehydrogenases/reductases (SDR) constitute a superfamily of proteins catalysing reactions of a wide range of substrates in all life forms. During the past years, a large number of new proteins belonging to this superfamily has been detected. They are important in e.g. LÄS MER

  4. 9. Hundraårsflöden : översvämningsskildringar i svensk samtidsprosa

    Författare :Malin Löf Nyqvist; Annelie Bränström Öhman; Maria Lindgren Leavenworth; Jerry Määttä; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Flood fiction; speculative fiction; climate fiction; disaster novels; ecocriticism; econarratology; blue humanities; deluge; Mikael Niemi; Conny Palmkvist; Nils Håkanson; Mats Söderlund; Översvämningsfiktion; spekulativ fiktion; klimatfiktion; katastrofromaner; ekokritik; ekonarratologi; blå humaniora; syndaflod; Mikael Niemi; Conny Palmkvist; Nils Håkanson; Mats Söderlund; Literature; litteraturvetenskap;

    Sammanfattning : The flood motif is one of the oldest in literary history, stretching back to the deluge myths in many cultures. It has influenced Western culture throughout the ages, perhaps most notably in the form of the biblical story about Noah’s Ark, continuously taking on new forms and connotations. LÄS MER

  5. 10. Partial methane oxidation from electronic structure calculations

    Författare :Adam Arvidsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ZSM-5 zeolite; density functional theory; microkinetic modelling; Mo6S8 cluster; partial methane oxidation;

    Sammanfattning : Investigating catalytic reactions with computational methods is a powerful approach to understand fundamental aspects of catalytic reactions and find ways to guide catalytic design. Partial methane oxidation is one example of a reaction with intriguing challenges, where a detailed atomistic approach may help to unravel the bottlenecks of this, as of yet, inefficient reaction.
