  2. 1. 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

  4. 2. Homing Endonucleases and Horizontal Gene Transfer in Bacteria and Bacteriophages

    Abstract : Homing endonuclease genes (HEGs) are selfish genetic elements that mediate their own super-Mendelian inheritance. This is mediated by the homing endonuclease cleavage of a HEG- allele followed by recombination-repair with a HEG+ allele.The majority of the HEGs are encoded in intervening sequences (IVSs).
