Magnetotactic bacteria (MTB) biomineralize intracellular magnetite (Fe3O4) crystals surrounded by a magnetosome membrane (MM). The MM contains membrane-specific proteins that control Fe3O4 mineralization in MTB. Previous studies have demonstrated Mms13 is critical protein within the MM. can be isolated from fraction of Magnetospirillum magneticum AMB-1 and homolog, MamC, has been shown to size ...
