摘  要:
趋磁细菌是一类能够沿着磁场方向运动的革兰氏阴性细菌的总称,其最显著的特征是能够在胞内合成特殊的原核细胞器——磁小体。磁小体是具有外膜包被、纳米级、在胞内成链状排列的Fe3O4或Fe3S4磁性颗粒,并且具有专属的形态、大小和排列。正是因为磁小体的这些特性使不同领域的科研工作者开发着趋磁细菌的应用。另外,磁小体可以作为生物矿化和原核生物形成膜细胞器的理想模型。趋磁细菌磁小体合成相关蛋白在磁小体囊泡的形成、铁的转运、成晶的控制以及胞内磁性颗粒的排列等过程中发挥作用。文中重点介绍了近年来发现的和趋磁细菌磁小体合成相关的蛋白,并对未来磁小体蛋白的研究进行了展望。

摘  要:
Magnetotactic bacteria are a kind of Gram-negative bacteria with the capability of swimming along geomagnetic field lines,the most distinguished characteristic of the bacteria in common is capable of synthesizing unique prokaryotic organelles-magnetosomes,which are membrane-enveloped,nano-sized crystals of Fe3O4 or Fe3S4 that are aligned in well-ordered intracellular chinas,and have species-specific morphologies,sizes and arrangements.Because of the special properties of these magnetic crystals,magnetotactic bacteria have been exploited for a variety of applications in diverse disciplines from geobiology to biotechnology.In addition,magnetosomes have served as a powerful model system for the study of biomineralization and prokaryotic organelles.The proteins associated with the formation of magnetosomes have functions in vesicle formation,magnetosomal iron transport,and the control of crystallization and intracellular arrangement of magnetite particles.The proteins associated with the formation of magnetosomes are discussed especially and the future research perspectives of magnetosomes' proteins are also proposed.
