From: Segregation of prokaryotic magnetosomes organelles is driven by treadmilling of a dynamic actin-like MamK filament

MamK-MamJ tracks drive magnetosome chain concatenation and repositioning. a Progression of a recently divided MC undergoing motion from the pole towards midcell conducted by the MamK-MamJ tracks due to the MamK incorporation to the filament at the cell poles and further treadmilling growth. b Stepwise magnetosome concatenation into a linear chain driven by MamK filament treadmilling and its interaction with MamJ. c Models depicted in “a” and “b” show only one filament. However, it is known that MamK forms filament bundles that flank the MC. Steps 1 to 3 represent the putative dynamics and interactions of MamK, MamJ, and magnetosomes during MC assembly and/or transport
