2. 1. Vitreoscilla Haemoglobin. Genetic Fusions and Metabolic Characterisation

   Author : Viktoria Roos; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Metabolism; Biokemi; metabolism; osmotic stress; transcript profiling; DNA microarrays; random elongation mutagenesis; directed evolution; mRNA structure; Vitreoscilla haemoglobin VHb ; Escherichia coli; salt stress.;

   Abstract : Vitreoscilla is an obligate aerobic bacterium living in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla expresses a homodimeric haemoglobin (VHb) when subjected to oxygen-limited conditions. READ MORE

4. 2. Diversity of thermostable DNA enzymes from Icelandic hot springs

   Author : Sigridur Hjorleifsdottir; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermophiles; microbial diversity; SSU rRNA; Thermus; hot springs; Biotechnology; Bioteknik; Biochemistry; enzymologi; Proteiner; enzymology; metabolism; Proteins; DNA enzymes; Biokemi;

   Abstract : The diversities of bacteria as well as thermostable DNA enzymes in Icelandic hot springs were studied using different techniques. First of all the bacterial diversity of different microbial mats as well as sediment samples was described by using both molecular methods and cultivation methods. READ MORE

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

   Author : Ny Qian; Teknisk mikrobiologi; []
   Keywords : 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;

   Abstract : 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.

6. 4. Influence of cisplatin on RNA structure in solution Escherichia coli tRNA(Ala) and human Wnt-5a 3' UTR model system studies

   Author : Pal Papsai; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biokemi; metabolism; Proteins; enzymology; Proteiner; enzymologi; Metabolism; Biochemistry; Naturvetenskap; Natural science; tRNA.; siRNA; probing RNA structure in solution; alanyl-tRNA synthetase; cisplatin;

   Abstract : RNA molecules in the cellular environment have several important functions. In many cases, proper RNA function is intimately linked to proper three-dimensional structure of the molecule. Thus, it seems reasonable to assume that structural changes caused by external influence can strongly inhibit important cellular functions maintained by RNAs. READ MORE

7. 5. On the antiporter-like subunits of respiratory chain Complex I - implications for the evolution and coupling mechanism of the NADH:quinone oxidoreductase enzyme complex

   Author : Cecilie Mathiesen; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biokemi; metabolism; Biochemistry; mrp; electron transport; respiration; membrane protein;

   Abstract : Complex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. READ MORE
