  1. 1. Cyanobacterial Hydrogen Metabolism : Regulation and Maturation of Hydrogenases

    Författare :Ellenor Devine; Peter Lindblad; Karin Stensjö; Laurent Cournac; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; hydrogenase; hydrogenase specific protease; maturation; regulation; transcriptional studies; hupW; hoxW; hyp; NtcA; CalA; Biology; Biologi; Molecular biology; Molekylärbiologi; Microbiology; Mikrobiologi; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    Sammanfattning : In times with elevated CO2 levels and global warming there is a need of finding alternatives to carbon based energy carriers. One such environmental friendly solution could be H2 produced by living organisms. LÄS MER

  3. 2. Allosteric Regulation of mRNA Metabolism : -Mechanisms of Cap-Dependent Regulation of Poly(A)-specific Ribonuclease (PARN)

    Författare :Per Nilsson; Anders Virtanen; Megerditch Kiledjian; Uppsala universitet; []
    Nyckelord :Cell and molecular biology; mRNA degradation; deadenylation; cap; poly A ; PARN; allosteric regulation; Cell- och molekylärbiologi;

    Sammanfattning : Degradation of mRNA is a highly regulated step important for proper gene expression. Degradation of eukaryotic mRNA is initiated by shortening of the 3’ end located poly(A) tail. Poly(A)-specific ribonuclease (PARN) is an oligomeric enzyme that degrades the poly(A) tail with high processivity. LÄS MER

  4. 3. Systems biology techniques show high prevalence of post-translational regulation in the cyanobacterium Synechocystis PCC 6803

    Författare :Jan Karlsen; Elton Paul Hudson; Martin Hagemann; KTH; []
    Nyckelord :systems biology; sustainable development; omics; ribosome profiling; RNA sequencing; proteomics; genetic engineering; bioproduction; cyanobacteria; gene regulation; metabolism; translational regulation; post-translational regulation; bioinformatics; Bioteknologi; Biotechnology;

    Sammanfattning : Earth's climate has been upset by carbon dioxide (CO2) emissions from human activities and the use of fossil resources. To prevent catastrophic events on the environment and on civilizations, we urgently need to develop alternative solutions that utilize renewable resources. LÄS MER

  5. 4. A beta-phosphoglucomutase in carbohydrate metabolism of Lactococcus lactis

    Författare :Ny Qian; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; gene regulation; beta-phosphoglucomutase; maltose metabolism; lactate; metabolic engineering; alpha-phosphoglucomutase; Lactococcus lactis; Microbiology; virology; bacteriology; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : Phosphoglucomutase (PGM) catalyzes the reversible conversion of glucose 1-phosphate to glucose 6-phosphate. Two distinct forms of PGM have been purifed and charactierized in Lactococcus lactis growing on maltose: one specific for the alpha-isomer, and the other specific for the beta-isomer of glucose 1-phosphate.

  7. 5. Plant UDP-glucose Pyrophosphorylase : Function and Regulation

    Författare :Meng Meng; Leszek Kleczkowski; Javier Pozueta-Romero; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UDP-glucose pyrophosphorylase; carbohydrate metabolism; in vivo regulation; T-DNA knockout; heterologous expression; isozyme; mutagenesis; kinetic property; oligomerization; Plant physiology; Växtfysiologi;

    Sammanfattning : UDP-glucose pyrophosphorylase (UGPase) is an important enzyme of carbohydrate metabolism in all living organisms. The main aim of this thesis was to investigate the function and regulation of plant UGP genes as well as the UGPase proteins. LÄS MER
