  1. 1. The Bacillus subtilis GlpP protein, antitermination and mRNA stability

    Författare :Elisabeth Glatz; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; leader sequence; glpD; GlpP; catabolite repression; mRNA stability; Bacillus subtilis; antiterminator protein; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Bacillus subtilis can grow on glycerol or glycerol-3-phosphate (G3P) as the sole carbon and energy source. The glpD gene encodes G3P dehydrogenase which is required for the catabolism of glycerol and G3P. LÄS MER

  3. 2. Global Regulation of Snf1 in Saccharomyces cerevisiae: A case study of experimental systems biology

    Författare :Jie Zhang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AMP-activated protein kinase AMPK ; glucose derepression; energy homeostasis; target of rapamycin complex 1 TORC1 ; catabolite repression; Snf1;

    Sammanfattning : Cells commonly face environmental changes and have evolved various regulatory mechanisms to adjust their metabolism accordingly. One such key regulator in S. cerevisiae is the Snf1 kinase, which belongs to the conserved AMP-activated protein kinase (AMPK) family in all eukaryotes. LÄS MER

  4. 3. Multiple regulatory inputs for hierarchical control of phenol catabolism by Pseudomonas putida

    Författare :W. K. Anjana Madhushani; Victoria Shingler; Livia Leoni; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; P. putida; Phenol catabolism; dmpR; dmp-System; 5’-LR; Carbon Catabolite Repression; Transcriptional Translational regulation; Crc; CrcZ; CrcY; Hfq;

    Sammanfattning : Metabolically versatile bacteria have evolved diverse strategies to adapt to different environmental niches and respond to fluctuating physico-chemical parameters. In order to survive in soil and water habitats, they employ specific and global regulatory circuits to integrate external and internal signals to counteract stress and optimise their energy status.

  5. 4. Catabolism of Pyrimidines in Yeast

    Författare :Anna Rasmussen; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pyrimidine degradation; catabolism of pyrimidines; nucleic acid precursors; yeast; Lachancea kluyveri; URC pathway;

    Sammanfattning : Pyrimidines are important precursors for nucleic acids, and constantly synthesized and degraded in the cell to maintain a balanced supply. Many microoganisms can also extract the nitrogens from the pyrimidine ring, and use them as a nitrogen source when “preferred” sources are absent. LÄS MER

  7. 5. Strategies for improved Escherichia coli bioprocessing performance

    Författare :Johan Jarmander; Gen Larsson; Thomas Egli; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E. coli; Salmonella; surface expression; autotransport; AIDA-I; lignocellulose; glucose; xylose; arabinose; simultaneous uptake; 3HB; Bioteknologi; Biotechnology;

    Sammanfattning : Escherichia coli has a proven track record for successful production of anything from small molecules like organic acids to large therapeutic proteins, and has thus important applications in both R&D and commercial production. The versatility of this organism in combination with the accumulated knowledge of its genome, metabolism and physiology, has allowed for development of specialty strains capable of performing very specific tasks, opening up opportunities within new areas.
