Research progress on synthesis mechanism of magnetosome in magnetotactic bacteria

摘要:

趋磁细菌可在环境中吸收大量铁并在细胞内合成纳米级磁性颗粒—磁小体。比较几种趋磁细菌基因组特征, 针对磁小体岛及与磁小体合成相关基因功能特点等方面, 综述了当前磁小体合成机制的研究进展。

Abstract:

Magnetotactic bacteria can absorb abundant ferrum from surroundings and synthesize nano- magnetic particle termed magnetosome in cells. Genome features of several kinds of magnetotactic bacteria are compared in this review and current research progress on synthesis mechanism of magnetosome are summarized in aspects of magnetosome island and functions of magnetosome-associated genes.
