1. 21. Enzyme immobilization in mesoporous silica

   Författare :Hanna Gustafsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pH probe; Mesoporous silica; particle morphology; immobilization; pore size; quartz crystal microbalance with dissipation monitoring; enzyme; biocatalysis;

   Sammanfattning : Enzymes are highly effective and versatile biological catalysts, with a high chemo-, stereo- and regioselectivity while operating under mild conditions, such as physiological temperature and pH and atmospheric pressure. Therefore, enzymes are a sustainable alternative to conventional catalysts in organic synthesis processes. LÄS MER

3. 22. The mitochondrial processing peptidase-cytochrome bc₁ complex of S. oleracea

   Författare :Sara Sjöling; Walter Neupert; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

   Sammanfattning : Proteins function at distinct sites within the cell, yet most of them are encoded by the nucleus and synthesised in the cytosol. Thus, newly synthesised mitochondrial proteins have to be transported within the cell. LÄS MER

4. 23. Organic Bioelectronic Devices for Selective Biomarker Sensing : Towards Integration with Living Systems

   Författare :Chiara Diacci; Magnus Berggren; Daniel Simon; Francesca Santoro; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Inorganic materials have been the main players of the semiconductor industry for the past forty years. However, there has been a continuous interest and growth in the research and in the application of organic semiconductors (OSCs) as active materials in electronic devices, due to the possibility to process these materials at low temperature on flexible substrates, fabricate them on large-area, and upscale their fabrication using cost-effective strategies such as printing.

5. 24. To metal, or not to metal : Diverse mechanisms of O2-activation and radical storage in the ferritin superfamily

   Författare :Vivek Srinivas; Martin Högbom; Brian Hoffman; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metalloprotein; di-metal; Oxygen activation; Substrate oxidation; Ribonucleotide reductase; Radical; DOPA; ADE-DOT; X-Ray free-electron laser; soluble Methane monooxygenase; Biochemistry; biokemi;

   Sammanfattning : Proteins in the Ferritin-like superfamily are characterized by a four alpha-helical structural motif. These proteins are distributed across all three kingdoms of life and perform a wide range of functions. LÄS MER

7. 25. Laccase from a Litter Degrading Fungus: Evaluation for Environmental Applications and Modification of Lignin to a Bioadhesive

   Författare :Victor Ibrahim; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Laccase, the phenol oxidizing enzyme, was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes single electron transfer oxidation in the presence of molecular oxygen producing water as by-product.
