BMC Microbiology, 2021 Background Magnetosome formation in the alphaproteobacterium Magnetospirillum gryphiswaldense is controlled by more than 30 known mam and mms genes clustered within a large genomic region, the ‘magnetosome island’ (MAI), which also harbors numerous ...

Detection of interphylum transfers of the magnetosome gene cluster in magnetotactic bacteria
Frontiers in Microbiology, 2022 Magnetosome synthesis in magnetotactic bacteria (MTB) is regarded as a very ancient evolutionary process that dates back to deep-branching phyla. Magnetotactic bacteria belonging to one of such phyla, Nitrospirota, contain the classical genes for the ...

McaA and McaB control the dynamic positioning of a bacterial magnetic organelle
Nature Communications, 2022 Magnetotactic bacteria use intracellular chains of ferrimagnetic nanocrystals, produced within magnetosome organelles, to align and navigate along the geomagnetic field. Here, Wan et al.

Dynamic Remodeling of the Magnetosome Membrane Is Triggered by the Initiation of Biomineralization
mBio, 2016 Magnetotactic bacteria produce chains of membrane-bound organelles that direct the biomineralization of magnetic nanoparticles. These magnetosome compartments are a model for studying the biogenesis and subcellular organization of bacterial organelles ...

Elastic Properties of Magnetosome Chains [PDF]
Biophysical Journal, 2015 Magnetotactic bacteria swim and orient in the direction of a magnetic field thanks to the magnetosome chain, a cellular ‘compass needle’ that consists of a string of vesicle-enclosed magnetic nanoparticles aligned on a cytoskeletal filament. Here we investigate the mechanical properties of such a chain, in particular the bending stiffness. We determine

Magnetite Crystal Orientation in Magnetosome Chains [PDF]
Advanced Functional Materials, 2014 One‐dimensional magnetic nanostructures have magnetic properties superior to non‐organized materials due to strong uniaxial shape anisotropy. Magnetosome chains in magnetotactic bacteria represent a biological paradigm of such magnet, where magnetite crystals synthesized in organelles called magnetosomes are arranged into linear chains. Two‐dimensional

Magnetosome formation in prokaryotes
Nature Reviews Microbiology, 2004 Magnetotactic bacteria were discovered almost 30 years ago, and for many years and many different reasons, the number of researchers working in this field was few and progress was slow. Recently, however, thanks to the isolation of new strains and the development of new techniques for manipulating these strains, researchers from several laboratories ...
