  2. 1. Lipase selectivity in functional polyester synthesis

    Author : Cecilia Hedfors; Karl Hult; Romas Kazlauskas; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Abstract : Enzyme selectivity means that the enzyme´s preferences towards competing substrates will be different. In this thesis, the enzyme selectivity has been studied for utilization in synthesis of functionalized macromonomers. READ MORE

  4. 2. In vitro and in vivo approaches in the characterization of XTH gene products

    Author : Nomchit Kaewthai; Harry Brumer; Jocelyn Rose; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabiodopsis thaliana; Hordeum vulgare; plant cell wall; xyloglucan; glycoside hydrolase family 16; xyloglucan endo-transglycosylase hydrolase gene family; xyloglucan endo-hydrolase; heterologous protein expression; Pichia pastoris; T-DNA insertion; in situ XET XEH assay; high-througput screening; Plant physiology; Växtfysiologi; Biochemistry; Biokemi; Functional genomics; Funktionsgenomik; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Abstract : ABSTRACT The xyloglucan endo-transglycosylase/hydrolase (XTH) genes are found in all vascular and some nonvascular plants. The XTH genes encode proteins which comprise a subfamily of glycoside hydrolase (GH) family 16 in the Carbohydrate-Active enZYmes (CAZY) classification. READ MORE

  5. 3. Tuning the polylactide hydrolysis rate without introducing new migrants

    Author : Sofia Regnell Andersson; Minna Hakkarainen; Karin Jacobson; Ulrika Edlund; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polylactide; sterocomplex; plasticizer; degradation; degradation products; ESI-MS; Biochemistry; Biokemi; Polymer chemistry; Polymerkemi;

    Abstract : The possibility to control and tune the hydrolytic degradation rate of polylactide without introducing any new degradation products was investigated by subjecting polylactide with cyclic or linear oligolactic acid additives, and a stereocomplex between the L- and D-enantiomers of polylactide to hydrolytic degradation at 37 and 60 °C for up to 39 weeks. The degradation was monitored by measuring mass loss, molar mass changes, water uptake, changes of surface structure, crystallinity and thermal properties. READ MORE

  6. 4. c Cytochromes as Electron Carriers in Microbial Chlorate Respiration

    Author : Anna Smedja Bäcklund; Thomas Nilsson; Pia Ädelroth; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; c cytochrome; chlorate reduction; electron transport; Biochemistry; Biokemi; Kemi; Chemistry;

    Abstract : Microbial respiration of oxochlorates is important for the biotreatment of effluents from industries where oxochlorates are produced or handled. Several bacterial species are capable to use perchlorate and/or chlorate as an alternative electron acceptor in absence of oxygen. READ MORE

  7. 5. Two Types of Fibrils in ATTR Amyloidosis : Implications for Clinical Phenotype and Treatment Outcome

    Author : Elisabet Ihse; Per Westermark; Per Hammarström; Uppsala universitet; []

    Abstract : Systemic amyloidoses are a group of lethal diseases where proteins aggregate into fibrillar structures, called amyloid fibrils, that deposits throughout the body. Transthyretin (TTR) causes one type of amyloidosis, in which the aggregates mainly infiltrate nervous and cardiac tissue. READ MORE
