The potassium binding that occurs during passive accumulation by intact Escherichia coli has been demonstrated in a cell-free system. The data suggest that this binding is due largely to binding by the cell proteins in general and cannot be accounted for by the binding of a particular protein. The results are in accord with the view that the ion-exchange properties of protoplasmic poly-electrolyte determine the overall ionic composition of the cell.
在无细胞体系中证实了完整大肠杆菌在被动积累过程中发生的钾结合。这些数据表明，这种结合主要归因于细胞蛋白的结合，而不是特定蛋白质的结合。这些结果与细胞质多电解质的离子交换特性决定细胞整体离子组成的观点一致。
