Maintenance of internal pH and an electrochemical gradient in Trypanosoma brucei.


The internal pH value (pHi) of the long-slender bloodstream form of Trypanosoma brucei was estimated from the distribution of 14C-labeled 5,5-dimethyl-2,4-oxazolidinedione or 14C-labeled methyl amine between the intracellular space of the cells and the medium. The pHi of T. brucei remained relatively constant at 7.0-7.2 throughout an extracellular pH (pHo… (More)
