Genetic Regulation and Phenotypic Expression of the Properties of Biogenic Magnetic Nanoparticles in Magnetotactic Bacteria and Human

By employing the bioinformatics methods, we consider the similarity between the genes of magnetosome island of magnetotactic bacteria and human genes for establishing the degree of homology and determination of functional class of proteins. We analyze the most meaningful coincidences between the genes of magnetosome island of bacteria of Magnetospirillum gryphiswaldense and human genes. We uncover the essential smoothing mainly among proteins of functional class. The process of biomineralization of magnetite in МТB, namely MamВ, MamЕ, MamА, MamN, MamО, MamМ can’t be conducted without these proteins. They have the well known common functions or belong to the same family. The analysis of homologues of regulator proteins (what regulate a form, size and amount of parts of Fe3O4, and also regulate formation of chain and magnitosome vesicule) show that only one protein of MamК can be a hypothetical homologues with the human proteins. The research results demonstrate there is no class of regulatory proteins in humans. There is strict control on the size of genetic and structural characteristics of biogenic magnetite.
