1. 11. Immobilization of feruloyl esterases in mesoporous silica

   Författare :Christian Thörn; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mesoporous materials; Feruloyl esterases; Protein modeling; Biocatalysis; QCM-D; Hydroxycinnamic acids; Enzyme immobilization; Silica;

   Sammanfattning : Feruloyl esterases are a class of enzymes that can be used as biocatalysts for the modification of bioactive hydroxycinnamic acids. In industry, enzyme immobilization is often necessary to stabilize the enzymes and to allow their reuse. LÄS MER

3. 12. Angiotensin-converting enzyme in cardiovascular function and dysfunction

   Författare :Liza Ljungberg; Toste Länne; Karin Persson; Urban Alehagen; Thomas Kahan; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Angiotensin-converting enzyme (ACE) is a key enzyme in the renin-angiotensin system, converting angiotensin I to the vasoactive peptide angiotensin II, and degrading bradykinin. Angiotensin II is a multifunctional peptide, acting on a number of different tissues. LÄS MER

4. 13. Synthesis of xyloglucan oligo- and polysaccharides with glycosynthase technology

   Författare :Fredrika Gullfot; Harry Brumer; Tuula Teeri; Jerry Ståhlberg; Mats Martinelle; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycosynthase; xyloglucan; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; xyloglucanase; polysaccharide synthesis; Bioengineering; Bioteknik; Enzyme engineering; Enzymteknik; Bioorganical synthesis; Bioorganisk syntes; Biomaterials; Biomaterial;

   Sammanfattning : Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glycans in the cell wall of plants. Their structure is complex with intricate branching patterns, which contribute to the physical properties of the polysaccharide including its binding to and interaction with other glycans such as cellulose.

5. 14. Structure-Function Studies of Enzymes from Ribose Metabolism

   Författare :C. Evalena Andersson; Sherry Mowbray; Phil Evans; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; activation; isomerase; kinase; potassium; product inhibition; ribose; ribose 5-phosphate; x-ray crystallography; enzyme kinetics; fluorescence spectroscopy; protein structure; Molekylärbiologi; Molecular biology; Molekylärbiologi;

   Sammanfattning : In the pentose phosphate pathway, carbohydrates such as glucose and ribose are degraded with production of reductive power and energy. Another important function is to produce essential pentoses, such as ribose 5-phosphate, which later can be used in biosynthesis of nucleic acids and cofactors. LÄS MER

7. 15. Sensitivity, Noise and Detection of Enzyme Inhibition in Progress Curves

   Författare :Omar Gutierrez Arenas; Helena Danielson; Athel Cornish-Bowden; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Progress curves; limit of detection; Z -factor; primary screening; enzyme inhibition; error structure; sensitivity analysis; High-throughput screning; Biokemi;

   Sammanfattning : Starting with the development of an enzymatic assay, where an enzyme in solution hydrolysed a solid-phase bound peptide, a model for the kinetics of enzyme action was introduced. This model allowed the estimation of kinetic parameters and enzyme activity for a system that has the peculiarity of not being saturable with the substrate, but with the enzyme. LÄS MER
