  2. 1. Heme A synthase from Bacillus subtilis and Aeropyrum pernix

    Author : Anna Lewin; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heme A synthesis; heme A; heme A synthase; CtaA; cCtaA; cytochrome a; Aeropyrum pernix; Bacillus subtilis;

    Abstract : Respiration in animals, plants and many bacteria is dependent on heme A, which functions as a prosthetic group in a-type cytochromes (terminal energy-transducing oxidases in the electron transport chain that reduce molecular oxygen to water). Heme A synthase catalyses a chemically very demanding reaction, the conversion of one specific methyl side-group of heme O to a formyl group of heme A. READ MORE

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

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

    Abstract : 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.
