Biomineralization of magnet nanoparticles with bacterial symbionts of man

Bioinformational analysis of human’s bacterial symbionts (BS) to study the process of biomineralization of biogenic magnetic nanoparticles (BMN) was conducted. For this purpose in this paper a comparative analysis of amino acid sequences of proteins of magnetosome island of magnetotactic bacteria (MI MTB) with human BS proteins using the program "BLAST-online" was made. A number of human BS may be potential producers of magnetic nanoparticles as evidenced by the experimental work of other authors. Considering obtained results it was shown that the interaction between tumor cells and some strains of human’s BS may occur due to the forces of magnetic dipole interaction, occuring between the endogenous magnetic nanoparticles of tumor cells and endogenous magnetosensitive particles of bacteria.
