The cytoskeletal protein MamK is involved in:
Magnetotactic bacteria such as Magnetospirillum magneticum AMB-1 and gryphiswaldense biomineralize magnetic nanoparticles within lipid vesicles called magnetosomes to navigate chemical gradients in stratified water columns. Cytoskeletal protein MamK actin homolog is essential for organizing magnetosomes into linear chain maximizing dipole moment for efficient orientation. MamK polymerizes ATP dependently into filaments extending along cell long axis, forms scaffold similar MreB but dedicated. Adaptor protein MamJ interacts with magnetosome membrane proteins MamY and MamK linking vesicles to fi
