2. 6. Functional studies of a membrane-anchored cellulase from poplar

   Author : Ulla Jonsson Rudsander; Tuula Teeri; Eva Nordberg-Karlsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Populus; cellulose biosynthesis; endo-1; 4-b-glucanase; cellulase; Pichia pastoris; Arabidopsis thaliana; NMR spectroscopy; cleavage pattern; stereochemistry; transglycosylation; complementation; hybrid proteins; overexpression; substrate analysis; overglycosylation; Bioengineering; Bioteknik;

   Abstract : Cellulose in particular and wood in general are valuable biomaterials for humanity, and cellulose is now also in the spotlight as a starting material for the production of biofuel. Understanding the processes of wood formation and cellulose biosynthesis could therefore be rewarding, and genomics and proteomics approaches have been initiated to learn more about wood biology.

4. 7. Making Analogues of Tröger's Base – Fused oligomers, endo/exo isomers and twisted amides

   Author : Josep Artacho Ruiz; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The centenarian Tröger’s base (TB) was envisaged as scaffold for the construction of tubular-shaped cleft molecules due to its the remarkable structural properties. This endeavor started with the synthesis of the three possible diastereomers of a linear symmetrically fused tris-TB analogue, the anti-anti, the syn-syn, and the syn-anti. READ MORE

5. 8. An Alkaline Active Endo-Xylanase from Bacillus halodurans S7:Molecular and Structural Aspects

   Author : Gashaw Mamo; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; Biokemisk teknik; mutagensis; Biochemical technology; xylanase structure; glycoside hydrolase family 10 cloning; Bacillus halodurans; Xylanase; alkaliphiles;

   Abstract : A strain of an alkaliphilic bacterium Bacillus halodurans was isolated from a water sample in Lake Shalla, a soda lake in the Ethiopian Rift Valley. From the culture of this isolate, B. halodurans S7, a xylanase which is active in a wide range of pH, with an optimum at about 9-9.5 was purified. READ MORE

6. 9. Evaluation of the Endo-Lysosomal System and the Ubiquitin-Proteasome System in Neurodegenerative Diseases

   Author : Simon Sjödin; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; Parkinson’s disease; frontotemporal dementia; dysfunctional proteostasis; cerebrospinal fluid; mass spectrometry;

   Abstract : Neurodegeneration is the process of neuronal cell loss where the symptoms will reflect the regions affected. Neurodegenerative disorders including Alzheimer’s disease (AD), Parkinson’s disease (PD) and frontotemporal dementia (FTD) are all characterised by an accumulation of protein aggregates suggesting impaired production or turnover of these proteins.

7. 10. On the engineering of proteins: methods and applications for carbohydrate-active enzymes

   Author : Fredrika Gullfot; Harry Brumer; Antoni Planas; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzyme engineering; rational design; directed evolution; DNA shuffling; glycosynthase; xyloglucan; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; xyloglucanase; carbohydrate binding module; polysaccharide synthesis; Bioengineering; Bioteknik;

   Abstract : This thesis presents the application of different protein engineering methods on enzymes and non-catalytic proteins that act upon xyloglucans. Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glucans in the cell wall of plants. READ MORE
