细菌细胞,像它们的真核生物一样,能够构建基于脂质的细胞器,执行基本的生化功能。趋磁细菌的磁小体就是这样一个隔间,它正迅速成为探索细菌细胞器生物发生过程的模型。磁小体由容纳磁性晶体的脂质双层隔室组成。通过将磁小体排列成细胞内的链,趋磁细菌创造了一个内部指南针,用于沿着磁场导航。在过去的十年中,许多研究已经阐明了磁小体膜的形成和磁性矿物的生物矿化的可能因素。在这里,我们强调了这些最新进展,特别关注磁小体形成的细胞生物学。
Bacterial cells, like their eukaryotic counterparts, are capable of constructing lipid-based organelles that carry out essential biochemical functions. The magnetosomes of magnetotactic bacteria are one such compartment that is quickly becoming a model for exploring the process of organelle biogenesis in bacteria. Magnetosomes consist of a lipid-bilayer compartment that houses a magnetic crystal. By arranging magnetosomes into chains within the cell, magnetotactic bacteria create an internal compass that is used for navigation along magnetic fields. Over the past decade, a number of studies have elucidated the possible factors involved in the formation of the magnetosome membrane and biomineralization of magnetic minerals. Here, we highlight some of these recent advances with a particular focus on the cell biology of magnetosome formation.
