  2. 1. Cytochrome c biogenesis in Bacillus subtilis. Identification and analysis of ccdA

    Author : Torbjörn Schiött; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spore synthesis; haem C; cytochrome c synthesis; Bacillus subtilis; ccdA; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Cytochromes function in electron transfer reactions, e.g. in respiratory systems, and contain haem as a prosthetic group. Cytochromes of the c-type differ from other cytochromes in that haem is covalently attached, via thioether linkages, to two cysteine residues in a conserved sequence motif in the protein, Cys-Xaa-Yaa-Cys-His.

  4. 2. Genetics of Tetrapyrrole Synthesis in Gram-Positive Bacteria

    Author : Per Johansson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; siroheme; tetrapyrrole synthesis; Bacillus subtilis; Bacillaceae; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The organization and regulation of genes for tetrapyrrole synthesis were studied in low G+C Gram-positive bacteria. Clusters of genes encoding enzymes for tetrapyrrole biosynthesis were cloned from Bacillus sphaericus, Bacillus stearothermophilus, Brevibacillus brevis and Paenibacillus macerans. READ MORE

  5. 3. Dynamic Organization of Molecular Machines in Bacteria

    Author : Bhupender Singh; Santanu Dasgupta; Leif A. Kirsebom; Don G. Ennis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular machines; bacteria; cell cycle; ribosome; replisome; divisome; spore; E. coli; H. pylori; Mycobacteria; Microbiology; Mikrobiologi; Mikrobiologi; Microbiology;

    Abstract : Bacterial cells were once treated as membrane-enclosed bags of cytoplasm: a homogeneous, undifferentiated suspension in which polymers (proteins, nucleic acids, etc.) and small molecules diffused freely to interact with each other. READ MORE

  6. 4. Symbiosis in Arbuscular Mycorrhizal Fungi : Unearthing genomic signatures

    Author : Shadi Eshghi Sahraei; Anna Rosling; Vasilis Kokkoris; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; arbuscular mycorrhizal fungi; mutualistic symbiosis; soil microeukaryotic communities; phylogenomics; single spore assembly; gene family evolution; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Arbuscular mycorrhizal (AM) fungi have been on earth since 470 million years ago. AM fungi form mutualistic symbiosis with most terrestrial plants and thus, are thought to have played important roles in land colonization together with plants. READ MORE

  7. 5. On the role of penicillin-binding protein SpoVD in endospore cortex assembly

    Author : Ewa Bukowska-Faniband; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sporulation; cortex; Bacillus subtilis; penicillin-binding proteins; SpoVD; peptidoglycan;

    Abstract : Bacteria of the genera Bacillus and Clostridium can form endospores as a strategy to survive unfavourable environmental conditions. Endospore formation involves synthesis of cortex, a thick layer of modified peptidoglycan that surrounds the spore. READ MORE
