we have measured the capacity of pseudomonas fluorescens to transport the glucose analog 2-deoxy-d-glucose and the amino acids l-alanine and alpha-aminoisobutyric acid under conditions in which the cells could generate ( i ) both a membrane proton motive force and high-energy phosphate compounds , ( ii ) a proton motive force but not high-energy phosphate compounds , and ( iii ) neither a proton motive force nor high-energy phosphate compounds .
