Individual segmented structures are depicted in different colors in the EMDB entry image and in the corresponding publication: Putative PopZ filaments are purple. Magnetite crystals are red, magnetosome membrane vesicles are yellow, and the cellular envelope inner and outer membranes are depicted in blue. MamK filaments are green.
Magnetospirillum gryphiswaldense MSR-1 PopZ 1
The polar organizing protein Z (PopZ) forms a polar microdomain that is inaccessible to larger macromolecules such as ribosomes, and selectively sequesters proteins crucial for cell cycle control and polar morphogenesis in various Alphaproteobacteria. In the present Magnetospirillum gryphiswaldense delta-popZ strain (lacking the endogenous popZ gene) PopZ overproduction was achieved via genomic insertion of a Tn5-Ptet-based popZ overexpression cassette.
Magnetospirillum gryphiswaldense MSR-1 Magnetosomes 1
Magnetosomes are membranous organelles containing nanometer-sized crystals of magnetite present in magnetotactic bacteria.

The filament-forming bacterial actin MamK found in magnetotactic bacteria is important for organizing magnetosome organelles into chains that are used for navigation along geomagnetic field lines.
