摘要

Nies 等人的一项新研究（J Bacteriol 206:e00080-24, 2024, https://doi.org/10.1128/jb.00080-24）提供了一组丰富的定量数据，说明了金属铜绿菌（Cupriavidus metallidurans）细胞的锌积累情况，包括缺乏导入或外排基因的突变菌株，并比较了先前缺乏金属的细胞与锌富集细胞的锌积累情况。这些数据令人惊讶地证明了活性金属导入和金属外排系统的同时活性。他们提出了一个流动平衡模型来描述细菌中的锌平衡。

In a state of flux: new insight into the transport processes that maintain bacterial metal homeostasis.

A new study by Nies et al. (J Bacteriol 206:e00080-24, 2024, https://doi.org/10.1128/jb.00080-24) provides a rich, quantitative data set of zinc accumulation by cells of Cupriavidus metallidurans, including of mutant bacterial strains lacking import or efflux genes, and comparison of zinc accumulation by cells previously starved of metal with those of zinc-replete cells. The data surprisingly demonstrate the concomitant activity of both active metal import and metal efflux systems. They present a flow equilibrium model to describe zinc homeostasis in bacteria.
