Cellular Distribution and Motion of Essential Magnetosome Proteins Expressed in Mammalian Cells [PDF]
BiosensorsMagnetosomes are organelle-like structures within magnetotactic bacteria that store iron biominerals in membrane-bound vesicles. In bacteria, formation of these structures is highly regulated by approximately 30 genes, which are conserved throughout ...

Current view of iron biomineralization in magnetotactic bacteria
Journal of Structural Biology: X, 2021 Biomineralization is the process of mineral formation by living organisms. One notable example of these organisms is magnetotactic bacteria (MTB). MTB are Gram-negative bacteria that can biomineralize iron into magnetic nanoparticles. This ability allows
