   Abstract : Thiopurine S-methyltransferase (TPMT) belongs to the Class I S-adenosylmethionine-dependent methyltransferase (SAM-MT) super family of structurally related proteins. Common to the members of this large protein family is the catalysis of methylation reactions using S-adenosylmethionine (SAM) as a methyl group donor, although SAM-MTs act on a wide range of different substrates and carry out numerous biologically important functions.

4. 7. Feruloyl esterases - Evaluation of their potential for biotechnological applications

   Author : Cyrielle Bonzom; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-domain enzyme; acetyl esterase; enzyme immobilization; N-glycosylation; carbohydrate active enzyme family 1; acetyl xylan esterase; heterologous production; polysaccharide utilization loci; enzyme stability; feruloyl esterase;

   Abstract : Owing to the current efforts to find sustainable alternatives to petrochemical based industries and technologies, enzymatic degradation and valorization of plant biomass has been attracting interest. Due to the complexity of plant biomass, an array of enzymes is required to hydrolyze it, including esterases. READ MORE

5. 8. Spectroscopic studies of biomolecules confined in self-assembled nanostructures

   Author : Nils Carlsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The present thesis examines the effects of incorporating biomolecules into self-assembled nanostructures. This approach is exemplified by short DNA molecules in environments close to lipid bilayers and the immobilization of enzymes into mesoporous silica particles. READ MORE

6. 9. Lipase-catalyzed production of structured triacylglycerols

   Author : Ariana Causevic; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structured lipids; Lipase; Acyl migration; Immobilization; Lipid analysis; Transesterification; Water activity;

   Abstract : Vegetable oils and fats are major energy sources but also play an essential part in the physical and chemical properties of food products. The current change in the climate is affecting harvest yields, leading to a shortage and increased prices of raw materials that are difficult to replace. READ MORE

7. 10. Biorefining of lignocellulose : Detoxification of inhibitory hydrolysates and potential utilization of residual streams for production of enzymes

   Author : Adnan Cavka; Leif J. Jönsson; John N. Saddler; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Lignocellulosic biomass is a renewable resource that can be utilized for the production of biofuels, chemicals, and bio-based materials. Biochemical conversion of lignocellulose to advanced biofuels, such as cellulosic ethanol, is generally performed through microbial fermentation of sugars generated by thermochemical pretreatment of the biomass followed by an enzymatic hydrolysis of the cellulose.
