The nature of the energy source for phosphate transport was studied in strains of Escherichia coli in which either one of the two major systems (PIT, PST) for phosphate transport was present. In the PIT system, phosphate transport is coupled to the proton-motive force. The energy source for the PST system appears to be phosphate-bond energy, as has been found in other systems involving binding proteins. High concentration gradients of phosphate (between 100 and 500) are established by both systems.
在大肠杆菌菌株中研究了磷酸盐转运能量来源的性质，这些菌株中存在两种主要的磷酸盐转运系统（PIT、PST）之一。在PIT系统中，磷酸盐转运与质子动力相偶联。正如在其他涉及结合蛋白的系统中所发现的那样，PST系统的能量来源似乎是磷酸键能。两种系统都能建立高浓度的磷酸盐梯度（在100至500之间）。
