  2. 1. Exotic Ribosomal Enzymology

    Author : Josefine Liljeruhm; Anthony C. Forster; Christophe Danelon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; rRNA modification; Methyltransferase; RlmM; RlmJ; D-amino acid; Unnatural amino acid; Chromoprotein; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : This thesis clarifies intriguing enzymology of the ribosome, the multiRNA/multiprotein complex that catalyzes protein synthesis (translation). The large ribosomal RNAs (23S and 16S rRNAs in E. coli) are post-transcriptionally modified by many specific modification enzymes, yet the functions of the modifications remain enigmatic. READ MORE

  4. 2. Transglycosylation catalyzed by β-mannanases : Molecular aspects relevant for enzymatic synthesis

    Author : Johan Morrill; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; β-mannanase; glycoside hydrolase; enzymology; kinetics; MALDI-TOF MS; HPLC; transglycosylation; alcoholysis; enzyme engineering; protein structure; enzymatic synthesis;

    Abstract : β-Mannanases are a major type of enzyme involved in the hydrolysis and modification of β-mannans, a hemicellulose present in high amounts in e.g. softwoods such as spruce. The β-mannanases studied in this thesis belong to glycoside hydrolase (GH) families GH5 and GH26. READ MORE

    Abstract : This thesis presents studies of molecular motors in interaction with nm-scale structures, as well as the development of a set of tools that can be used for the construction of custom-designed nano-transportation systems. In our studies, we have used the latest nanoscale technology and combined this with advanced results from chemistry and biomedical sciences. READ MORE

  6. 4. Molecular regulation of rat histidine decarboxylase

    Author : Christine Dartsch; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physiology; omeprazole; antiserum; fetal rat liver; COS-7 cells; purification; bacterial expression; protein turnover; ECL cells; gastric mucosa; gastrin; histdine decarboxylase; histamine; Fysiologi; Proteins; enzymology; Proteiner; enzymologi;

    Abstract : Histamine is involved in a variety of physiological processes like gastric acid secretion, inflammation and neurotransmission. The production of histamine is catalysed by the enzyme histidine decarboxylase (HDC), which is a strongly regulated enzyme. READ MORE
