Journal ArticleDOI
Magnetotactic bacteria form magnetite from a phosphate-rich ferric hydroxide via nanometric ferric (oxyhydr)oxide intermediates
Jens Baumgartner,Guillaume Morin,Nicolas Menguy,Teresa Perez Gonzalez,Marc Widdrat,Julie Cosmidis,Damien Faivre +6 more
TL;DR: It is shown that magnetite forms through phase transformation from a highly disordered phosphate-rich ferric hydroxide phase, consistent with prokaryotic ferritins, via transient nanometric ferric (oxyhydr)oxide intermediates within the magnetosome organelle.
Journal ArticleDOI
Magnetite Crystal Orientation in Magnetosome Chains
André Körnig,Michael Winklhofer,Jens Baumgartner,Teresa Perez Gonzalez,Peter Fratzl,Damien Faivre +5 more
TL;DR: Two-dimensional synchrotron X-ray diffraction is applied to cells of magnetotactic bacteria that are pre-aligned with a magnetic field to determine the crystallographic orientation of magnetosomes relative to the chain axis to reveal pronounced fiber textures that can be explained by a strain-specific biological control on crystal orientation at the chain level or by physical alignment effects due to intra-chain magnetic interactions.
Journal ArticleDOI
Structure-function studies of the magnetite-biomineralizing magnetosome-associated protein MamC
Hila Nudelman,Carmen Valverde-Tercedor,Sofiya Kolusheva,Teresa Perez Gonzalez,Marc Widdrat,Noam Grimberg,Hilla Levi,Or Nelkenbaum,Geula Davidov,Damien Faivre,Concepcion Jimenez-Lopez,Raz Zarivach +11 more
TL;DR: It is suggested that the connection between the MamC-MIL structure and the protein's charged surfaces is crucial for magnetite binding and thus for the size control of the magnetite nanoparticles.
Journal ArticleDOI
Elongated magnetite nanoparticle formation from a solid ferrous precursor in a magnetotactic bacterium.
Jens Baumgartner,Nicolas Menguy,Teresa Perez Gonzalez,Guillaume Morin,Marc Widdrat,Damien Faivre +5 more
TL;DR: These findings represent a novel observation in the interconversion of iron (oxyhydr)oxide materials and suggest that solid-state growth processes could be required to produce irregularly shaped, elongated magnetite nanocrystals.
