Examples of magnetosome in the following topics:

  • Magnetosomes

    • Each magnetite crystal within a magnetosome is surrounded by a lipid bilayer.
    • Magnetotactic bacteria usually mineralize either iron oxide magnetosomes , which contain crystals of magnetite (Fe3O4), or iron sulfide magnetosomes, which contain crystals of greigite (Fe3S4).
    • Magnetosome crystals are typically 35–120 nm long, which makes them single-domain.
    • In most magnetotactic bacteria, the magnetosomes are arranged in one or more chains.
