  1. 1. Engineering enzymes towards biotherapeutic applications using ancestral sequence reconstruction

    Författare :Natalie Hendrikse; Per-Olof Syrén; Johan Rockberg; Erik Nordling; Reinhard Sterner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; enzyme engineering; enzyme evolution; ancestral sequence reconstruction; therapeutic enzymes; terpene cyclases; ammonia-lyases; sulfatases; lysosomal enzymes; Kemi; Chemistry;

    Sammanfattning : Enzymes are versatile biocatalysts that fulfill essential functions in all forms of life and, therefore, play an important role in health and disease. One specific application of enzymes in life science is their use as biopharmaceuticals, which typically benefits from high catalytic activity and stability. LÄS MER

  3. 2. Sequence- and structure guided engineering of proteins and enzymes for biotechnology and health applications

    Författare :Karen Schriever; Per-Olof Syrén; Elton P. Hudson; Eric A. Gaucher; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein engineering; enzymology; ancestral sequence reconstruction; antigen engineering; structural biology; terpene cyclases; enzyme thermodynamics; biocatalysis; phosphatases; allosteric regulation; Biotechnology; Bioteknologi;

    Sammanfattning : Proteins are highly diverse and sophisticated biomolecules that represent a cornerstone of biological structure and function and have been exploited in man-made applications for thousands of years. Those proteins that facilitate chemical reactions at physiologically relevant time-scales are referred to as enzymes. LÄS MER

  4. 3. In silico protein design for the enhancement of protein stability and function

    Författare :David A. Hueting; Per-Olof Syrén; Hjalmar Brismar; Zbynek Prokop; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein Engineering; Ancestral sequence reconstruction; terpene cyclases; SARS-CoV-2; Spike protein; PET; PETase; rational engineering; Proteinteknik; Förfäders sekvensrekonstruktion; Terpencyklas; SARS-CoV-2; Spike protein; PET; PETas; rationell proteinteknik; Kemi; Chemistry;

    Sammanfattning : Enzymes are natures catalysts that increase the rate of a chemical reaction. The increased rate of a reaction is required to be able to sustain life. Despite the huge impact of enzymes, they are not perfect catalysts. LÄS MER

  5. 4. Evolution of Interactions Involving Intrinsically Disordered Proteins

    Författare :Emma Åberg; Per Jemth; Madan Babu; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; intrinsically disordered proteins; protein evolution; phylogenetics; ancestral sequence reconstruction; biophysical characterization; NCBD; CID; p53; MDM2; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Biokemi; Biochemistry;

    Sammanfattning : This thesis describes the evolution of intrinsically disordered proteins and their interaction partners. The work presented is a combination of phylogenetic analysis, ancestral reconstruction and biophysical characterization in order to examine the evolutionary trajectory of protein-protein interactions involving disorder.

  7. 5. Genomic Variation and Evolution of HERV-H and other Endogenous Retroviruses (ERVs)

    Författare :Patric Jern; Jonas Blomberg; Michael Tristem; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; Endogenous Retrovirus ERV ; HERV-H; Phylogeny; Evolution; Sequence Variation; Polymorphism; Recent Integrations; Horizontal Transfer; Master Elements; Taxonomy; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar;

    Sammanfattning : An exogenous retrovirus (XRV) that integrates into a germ cell may be inherited as a Mendelian gene; it becomes an endogenous retrovirus (ERV). The human genome consists of up to 8% HERVs. The gammaretroviral (ERV class I) HERV-H, with 926 members, is the largest ERV group. LÄS MER
