  1. 1. Genetics of Tetrapyrrole Synthesis in Gram-Positive Bacteria

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

    Sammanfattning : 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. LÄS MER

  2. 2. Tetrapyrrole synthesis in Bacillus subtilis

    Författare :Mats Hansson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes tetrapyrrole synthesis in the aerobic Gram positive bacterium Bacillus sub-tilis. Tetrapyrroles such as heme of a-, b-, c-, d- and o-type can be synthesised in this organism. In addition, there is strong evidence for the presence of the tetrapyrrole siroheme in B. subtilis.

  3. 3. Synthesis of hemes found in heme-copper oxidases of Bacillus subtilis

    Författare :Mimmi Throne-Holst; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Biologi; Biology; heme biosynthesis; respiratory oxidase; cytochrome; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The last step of aerobic respiration, the reduction of dioxygen to water, is catalysed by terminal oxidases. These oxidases can be divided into two unrelated families, the heme-copper oxidases and the cytochrome bd-type oxidases. These enzymes contain two or more heme molecules as prosthetic groups. LÄS MER
