Abstract
The representatives of Proteobacteria and Actinobacteria were classified into four groups according to the presence of homologues of Mam-protein magnetotacticum bacteria that provide a synthesis of biogenic magnetic nanoparticles (BMN), and ferritin and/or ferrite-like proteins by methods of bioinformatics analysis. In this work were fnalyzed the following factors that define a particular phenotype in bacteria types Proteobacteria and Actinobacteria: habitat, living conditions, mobility, presence of magnetic phases in the environment, mechanisms of cell-cell interactions. It is shown that BMN may provide magnototaxis, act as factor of specific cell-cell interactions and interactions with paramagnetic components of the environment, to ensure the capture and storage of efficiently paramagnetic and paramagnetic intracellular and externacellular components (granules, vesicles, vacuoles, and micro nanobulbashok etc.), protection of microorganisms cells from excess of iron ions and for patahens and conditional patahens availability of BMN provides protection against the host immune response. Thus the presence of BMN in microorganisms is a factor that increases the likelihood of their survival along with other organisms.
