magnetosome membrane (MM) proteins which play an important role in magnetite biomineralization.

magnetosome synthesis in Magnetospirillum gryphiswaldense MSR-1," Journal of Bacteriology, vol.
As shown in Figure 2, the XRD pattern of synthetic magnetic nanocrystal and
magnetosome matched well with the standard [Fe.sub.3][O.sub.4] reflections.
These bacteria form magnetite crystals as part of a
magnetosome (Fig.
Previous studies have shown that some
magnetosome chains would not be useful for navigation because their crystal sizes did not possess the right magnetic qualities.
Similarly, what a certain signal in the visual system of male hoverflies is supposed to represent is the nearness of fertile female hoverflies; what the signal in the snake's nervous system signifies, when triggered by the requisite combination of warmth and movement, is the presence of prey (perhaps specifically of a mouse); and what the
magnetosome represents (if anything)(11) is the direction of safe travel.

A detailed look at its DNA revealed that BW-1 has two sets of
magnetosome genes, unlike other such bacteria, which produce only one mineral and have only one set of
magnetosome genes.
