Magnetic Bacteria
We are investigating the formation of magnetosomes (membrane bound magnetite particles) in magnetotactic bacteria. This process is believed to take place in the following steps: i) production of invaginations along the inner membrane ii) uptake of iron into these invaginations iii) biomineralisation of the iron into magnetite crystals of a specific size and shape iv) axial alignment of the magnetosomes.
This mechanism gives the bacteria the ability to align itself like a compass needle along geomagnetic field lines. We are attempting to engineer the uptake of soluble iron into membrane invaginations in E.coli, and stimulate formation of magnetite using genes from Magnetospirillum.
